Practice: Chapter review: the read-aloud test (4 problems · doesn’t affect your progress)

Only one of these four stands on its own without you expecting anything else. Which one?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

"Since" sets up a because-then relationship that never lands — you're left waiting to hear what happened because the power went out.

Who painted the fence? This never names a subject at all, so the read-aloud test leaves you asking that question.

Try finishing the thought out loud: "once the guests leave..." then what? That's the piece "Once" promises and never delivers.

Why

"The train arrived at noon" names a subject (the train) and says something complete about it. The other three all leave you waiting for more information.

The train arrived at noon.

Read this aloud: "Whenever the printer runs out of ink." Does it sound finished, or does it leave you hanging?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

Try saying it out loud and stopping right there — most people naturally keep listening for what happens whenever the printer runs out of ink.

Why

"Whenever" sets up a moment that the sentence never describes. You'd expect something like "...the whole project stalls."

No, it leaves you waiting for what comes next.

Fill in the blank: every sentence needs a word that names who or what it's about — that word is called the ___.

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

Why

The subject is the who or what a sentence is about. "Marco's is a popular diner" — Marco's is the subject.

Correct answer

Also accepted:

Why

It's the same word this section used to describe what a sentence is "about."

subject

Out of these four, which one doesn't need anything else added to sound complete?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

No one is doing the sprinting here. Who sprinted across the field?

Though at the front leaves you waiting: though the rain continued, what happened?

This only tells you when. Nobody does anything, so it sounds unfinished.

Why

Only this one has a clear subject (the committee) and says something complete about it, with nothing left dangling.

The committee approved the budget.

Practice: Chapter review: naming the punctuation marks (4 problems · doesn’t affect your progress)

Tag each punctuation mark in this sentence with its correct name. Leave the words unlabeled.

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

Why

The two quotation marks (“ ”) wrap the exact word he said, and the question mark (?) shows he asked it. The semicolon (;) joins two independent clauses. The comma (,) comes before "and" where it joins two more. The period (.) ends the sentence.

Correct answer

Also accepted:

Why

word 1 ““” → quotation mark, word 3 “?” → question mark, word 4 “”” → quotation mark, word 7 “;” → semicolon, word 10 “,” → comma, word 15 “.” → period

This mark is a long horizontal line — longer than a hyphen — used to set information apart dramatically. Which mark is it?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

A hyphen is much shorter (-) and joins compound words like "well-known." This longer mark is a dash.

A colon (:) is two stacked dots, used to introduce a list or explanation — not a horizontal line.

An apostrophe (') is a small mark used for possession and contractions — not a horizontal line.

Why

The em dash (—) is a long horizontal mark used to set off information dramatically — longer than a hyphen (-), which only joins compound words.

em dash

You're about to introduce a list with a specific mark, like: "Pack these: a tent, a stove, and a lantern." Which mark is it?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

A semicolon joins two complete sentences. It doesn't announce a list.

An apostrophe marks ownership or a shortened word, like it's. It never introduces a list.

Commas separate the items inside the list, but the mark that announces the list is a different one.

Why

A colon (:) announces that a list, an explanation, or an example is about to follow — that's its one job.

colon

A sentence is phrased as a question. Which punctuation mark finishes it?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

A period ends a plain statement, not a question.

An exclamation point ends a sentence said with strong feeling, not one that asks something.

A comma never ends a sentence; it separates parts inside one.

Why

A question mark (?) ends a sentence that asks something. A period (.) ends a statement; an exclamation point (!) ends a sentence said with strong feeling.

Practice: Chapter review: the two boundary signals (4 problems · doesn’t affect your progress)

These two sentences run together with nothing showing where one ends and the next begins. Click the first word and the last word of the FIRST sentence only.

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

What this task checks

Structure checked automatically. Whether your ideas are convincing isn't graded, so reread with the checklist.

The compiler says

A model answer

Why

The first sentence runs from "the" through "onions" (again, uncapitalized here). "the soup simmered slowly" begins right after, with nothing marking the boundary.

Correct answer

Why

“the chef chopped onions” (words 1–4)

This sentence's boundary signals need fixing. Find them and fix them.

Why

A sentence needs both signals: a capital letter at the start ("Traffic") and an end mark at the finish (the period after "heavy").

Correct answer

Also accepted:

Why

after word 3 “heavy”: “.”; capitalize word 1 “traffic”

"Did the mail come?" starts with a capital letter and ends with a question mark, not a period. Does it have both boundary signals?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

The end-mark signal can be a period, a question mark, or an exclamation point. Any of the three marks the finish.

Questions start with a capital letter just like statements do. The capital marks the start of any sentence.

Why

The finish can be marked by a period, a question mark, or an exclamation point. "Did" carries the capital and the question mark closes it, so both signals are in place.

Yes — a question mark is one of the end marks, so the finish is signaled.

A note on the fridge reads "the train left on time" with no capital letter and no end mark. Which statement about it is true?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

The two checks look at different things. Say the words aloud by themselves: do they sound finished? The missing marks don't change that.

A complete thought is only half the story. The two-signal check looks for a capital and an end mark, and neither is here.

Flip it around. The words sound finished when you say them, but the page shows neither signal.

Why

"The train left on time" sounds finished when you say it, so it passes the read-aloud test. But the two-signal check only looks at the page, and there's no capital at the start and no end mark at the finish. The two checks can disagree, which is why you need both.

It passes the read-aloud test but fails the two-signal check.

Practice: Chapter review: noun or verb? (4 problems · doesn’t affect your progress)

Sort each word below into noun (names something) or verb (an action or state).

Correct! 🎉 Not quite.

Why

"Painter" and "mural" name people/things — nouns. "Finished" is the action the painter did — a verb. "The" and "slowly" aren't nouns or verbs at all.

Correct answer

Also accepted:

Why

word 2 “painter” → noun, word 3 “finished” → verb, word 5 “mural” → noun

In "The engine roared," which word is the verb?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

The just points at the engine. It doesn't say what anything did.

Engine names what did something. That makes it the noun, not the verb.

Why

"Roared" tells you what the engine did — that's the verb. "Engine" names what did it — that's the noun (and the subject).

roared

As a chapter review: in "My uncle and I fish at the lake," what job is "fish" doing?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

Ask what my uncle and I do. We fish. That's the action, so in this sentence it's a verb. In We ate fish for dinner, the same word would name a thing.

Spelling never decides the job. Fish is spelled the same as a noun and as a verb. The sentence around it decides.

Why

Ask what the subject does: my uncle and I fish. The word is the action, so here it's a verb. In We ate fish for dinner, the same spelling names a thing, so there it's a noun.

Verb: it says what my uncle and I do.

For review: in "The room felt cold," which word is the verb?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

The just points at the room. It doesn't say what the room does or is.

Room names what the sentence is about. It's the noun, the subject.

"Cold" describes the room, but it isn't doing the verb's job of saying what the subject does or is.

Why

"Felt" is a state-of-being verb here. Nothing is moving, but it still says something about the room's state, the same pattern as "seemed happy."

felt

As a chapter review: a grader writes "cap" next to the word i in "Then i left early." What does that mean?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

That's what "sp" means. The letter itself is right; it's the wrong size.

That's what "frag" means. Then I left early is a complete sentence.

That's what "awk" means. The sentence reads smoothly; one letter needs fixing.

Why

"cap" flags a capital letter to add or remove. The word I is always a capital, so the fix is Then I left early.

A capital letter needs to be added or removed.

Your grader marks a sentence with "frag." What's actually wrong with it?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

That's what "sp" means.

That's what "w.c." (word choice) means.

That's what "punc" means.

Why

"frag" is short for fragment — an incomplete sentence, often a dependent clause standing alone, or missing a subject or verb.

It's punctuated like a sentence but isn't actually complete.

"r.o." and "c.s." both mark two independent clauses stuck together. What's the actual difference between them?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

They mark two different joins. Look at what sits between the two sentences in each case.

Spelling gets sp and capitals get cap. Both of these marks are about how two sentences are joined.

Both marks can show up anywhere, in one sentence or a long essay. The difference is in how the join is made.

Why

"r.o." is a run-on — two independent clauses joined with no punctuation at all. (Chapter 11 adds a second kind of run-on.) "c.s." is a comma splice — the same two clauses joined by only a comma.

One join uses no punctuation at all; the other uses only a comma.

As a chapter review: every word in a sentence is spelled right and correctly chosen, but the sentence itself is hard to follow. Which mark fits?

Correct! 🎉 Not quite.

Right on try — credit. Right — the answer had already been shown, so no credit this time. Next try is worth Answer shown after three tries — this one no longer earns credit. You chose to see the answer — this one earns no credit.

Sp means a word is misspelled. Every word here is spelled right.

Punc flags a punctuation mistake. The trouble here is the wording.

"w.c." means the WRONG word was chosen. This sentence's words are all correct, just tangled together.

Why

"awk" is for a sentence that's grammatically fine but reads clumsily. "w.c." is reserved for an actually wrong word, a different problem entirely.

awk
