Question 1

The shift starts at nine I arrived at eight the door was locked.

Which choice fixes all sentence breaks without changing the meaning?

  1. The shift starts at nine. I arrived at eight the door was locked.
  2. The shift starts at nine, I arrived at eight, the door was locked.
  3. The shift starts. At nine I arrived. At eight the door was locked.
  4. The shift starts at nine. I arrived at eight. The door was locked. (correct answer)
Explanation: When you see a string of ideas run together without punctuation, your job is to find where each complete thought ends and a new one begins. A complete thought — called a sentence — has a subject and a verb and expresses one full idea. The original passage has three separate ideas crammed together: (1) when the shift starts, (2) when the speaker arrived, and (3) what the door was doing. Each needs its own sentence. Answer D is correct because it separates all three ideas with periods: "The shift starts at nine. I arrived at eight. The door was locked." Every group of words is a complete thought, and the meaning stays exactly the same. Answer A only adds one period after "nine," leaving "I arrived at eight the door was locked" as a run-on — two ideas still smashed together with no separation. Answer B uses commas between the three ideas, but commas alone cannot join independent sentences. This creates what's called a comma splice, which is still a punctuation error even though commas are involved. Answer C is the trickiest trap. It adds periods, but in the wrong places, splitting "The shift starts at nine" into "The shift starts." and "At nine I arrived." This changes the meaning entirely — now it sounds like the speaker arrived at nine, not eight. A good strategy: before choosing your answer, read each option aloud and ask yourself, "Does each sentence make sense on its own, and does it say the same thing as the original?" If a sentence feels incomplete or the meaning shifted, move on to the next choice.

Question 2

I wore gloves because the box was cold my hands stayed warm.

Which choice keeps because with the idea it explains and fixes the run-on?

  1. I wore gloves because. The box was cold. My hands stayed warm.
  2. I wore gloves because the box was cold. My hands stayed warm. (correct answer)
  3. I wore gloves. Because the box was cold my hands stayed warm.
  4. I wore gloves because the box was cold, my hands stayed warm.
Explanation: When you see a run-on sentence question, ask yourself: which words belong together, and where does one complete thought end and another begin? A run-on happens when two or more sentences are joined incorrectly — or not joined at all. Here, the word because is a connecting word that links a reason to an action. It answers the question "why?" — I wore gloves because the box was cold. That's one complete idea: the cold box explains why the gloves went on. My hands stayed warm is a separate result — its own complete thought. Choice B handles this perfectly. It keeps because attached to the words it explains ("the box was cold"), forming one solid sentence: I wore gloves because the box was cold. Then a period closes that thought, and My hands stayed warm stands on its own. No run-on, no broken meaning. Choice A breaks the sentence in the wrong place — cutting because away from its explanation entirely. Ending after "because" leaves an incomplete, dangling thought. Choice C moves because to the start of the second group, but then because the box was cold my hands stayed warm becomes its own run-on with no clear separation. Choice D adds a comma between the two main ideas, but a comma alone isn't strong enough to join two complete sentences — that's called a comma splice, which is still a run-on error. Study tip: When you see because, always keep it glued to the reason it introduces. Then check whether the remaining thought can stand alone — if so, give it its own sentence with a period.

Question 3

The store was open I could buy milk.

Which correction uses the joining word so correctly?

  1. The store was open, so. I could buy milk.
  2. The store was open so I could buy milk.
  3. The store was open, so I could buy milk. (correct answer)
  4. The store was open so, I could buy milk.
Explanation: When two complete thoughts are joined together, you need both a comma and a joining word (also called a coordinating conjunction) to connect them properly. The word so is a joining word that shows cause and effect — the first idea causes or leads to the second. The trick is knowing exactly where the comma and so belong. In the sentence "The store was open, so I could buy milk," the comma comes right before so, and then so leads directly into the second thought. That's choice C, and it's the correct way to join these two ideas. The comma signals a pause, so connects the cause and effect, and the sentence flows naturally. Choice A — "The store was open, so. I could buy milk" — puts a period after so, which cuts the sentence in half and leaves so hanging with nothing to connect to. That creates a fragment. Choice B — "The store was open so I could buy milk" — is missing the comma entirely. Even though the joining word is there, without the comma the sentence feels rushed and is punctuated incorrectly. Choice D — "The store was open so, I could buy milk" — puts the comma in the wrong place. The comma comes after the joining word, but it should always come before it. A helpful tip to remember: the comma always hugs the left side of the joining word. Think of it as comma, then connector — never the other way around.

Question 4

The bus is late I will call work.

Which choice best corrects the sentence?

  1. The bus is late, I will call work.
  2. The bus is late. I will call work. (correct answer)
  3. The bus is late I will call work.
  4. The bus is late. i will call work.
Explanation: When a sentence tries to express two complete thoughts but squishes them together without proper punctuation, it's called a run-on sentence. Fixing run-ons is a key writing skill, and the trick is finding where one complete thought ends and another begins. Look at the sentence: The bus is late I will call work. Ask yourself — does "The bus is late" make sense on its own? Yes. Does "I will call work" make sense on its own? Yes. That means you have two separate, complete thoughts that need to be properly separated. The best fix is answer B: The bus is late. I will call work. A period ends the first complete thought, and the second sentence begins with a capital "I." This is clean, correct, and easy to read. Here's why the other choices fall short. Answer A places a comma between the two complete thoughts — The bus is late, I will call work — but a comma alone isn't strong enough to join two full sentences. This mistake is called a comma splice, and it's still considered a run-on error. Answer C keeps the original sentence exactly as it is, with no punctuation fix at all, so the run-on problem remains. Answer D uses a period correctly but then writes i will call work with a lowercase "i" — every sentence must start with a capital letter, and "I" used alone is always capitalized. A helpful tip: whenever you spot a long sentence, pause and ask, "Could I split this into two sentences that each stand alone?" If yes, a period is usually your safest fix.

Question 5

Before the office opened we stood outside the guard unlocked the door.

Which choice adds both needed punctuation marks?

  1. Before the office opened, we stood outside the guard unlocked the door.
  2. Before the office opened we stood outside. The guard unlocked the door.
  3. Before the office opened, we stood outside. The guard unlocked the door. (correct answer)
  4. Before the office opened. We stood outside, the guard unlocked the door.
Explanation: When a sentence has multiple ideas, punctuation helps your reader know where one thought ends and another begins. Here, the original passage has three separate ideas crammed together with no punctuation at all, creating what's called a "run-on sentence." Your job is to find the choice that correctly separates all three ideas. Let's look at the structure: "Before the office opened" is an introductory clause — it sets up the scene but can't stand alone. "We stood outside" is a complete thought. "The guard unlocked the door" is another complete thought. A comma should follow an introductory clause, and a period should separate two complete, independent sentences. Choice C does exactly this: the comma after "opened" signals the end of the introductory clause, and the period after "outside" cleanly separates the two independent sentences. That makes C the correct answer. Choice A adds the comma after "opened" — good start — but leaves "we stood outside the guard unlocked the door" as one run-on sentence with no period to separate two complete thoughts. Choice B skips the comma after "opened" entirely, which leaves the introductory clause awkwardly attached without proper signaling, even though it does correctly add a period. Choice D is the most problematic: it places a period after "opened," which cuts off the introductory clause as if it were a complete sentence (it isn't), and then creates a comma splice by joining "We stood outside" and "the guard unlocked the door" with only a comma. A good tip: always check introductory clauses first — if a sentence starts with a dependent phrase like "Before..." or "When...", it almost always needs a comma before the main idea begins.

Question 6

The job was near my home I had to take two buses.

Which correction uses the joining word but with correct punctuation?

  1. The job was near my home, but. I had to take two buses.
  2. The job was near my home but I had to take two buses.
  3. The job was near my home, but I had to take two buses. (correct answer)
  4. The job was near my home but, I had to take two buses.
Explanation: When two complete thoughts are joined by a connecting word like but, and, or so, punctuation matters. These connecting words are called conjunctions, and but signals a contrast — something unexpected follows. The rule is simple: place a comma before the conjunction, not after it, and not in the middle of either complete thought. In the original sentence, "The job was near my home" and "I had to take two buses" are two complete ideas. The word but connects them while showing contrast (being close to home, yet still needing two buses). To join them correctly, you put a comma right before but: The job was near my home, but I had to take two buses. That's choice C, and it follows the rule perfectly. Now look at why the others fail. Choice A puts the comma before but correctly — but then adds a period after but, which cuts the sentence in half and leaves "I had to take two buses" as a fragment disconnected from the first idea. Choice B drops the comma entirely, which runs the two thoughts together without a proper pause — the reader has no signal that a contrast is coming. Choice D places the comma after but instead of before it, which breaks the rule; the comma belongs before the joining word, never after it. A handy tip: whenever you see but, and, or, so, or yet joining two complete sentences, ask yourself, "Is there a comma right before this word?" If yes — and only before it — the punctuation is correct.

Question 7

Wash the cup put it on the shelf.

Which choice correctly separates the two steps?

  1. Wash the cup. Put it on the shelf. (correct answer)
  2. Wash the cup, put it on the shelf.
  3. Wash the cup put it. On the shelf.
  4. Wash the cup. put it on the shelf.
Explanation: When a sentence contains two separate actions or steps, you need punctuation to show where one idea ends and the next begins. A period (.) is the standard way to end a complete sentence, and a capital letter signals the start of a new one. Keep both rules in mind as you look at this question. The original sentence runs two complete thoughts together without any separation: "Wash the cup" is one full instruction, and "put it on the shelf" is another. Choice A fixes this perfectly — it places a period after "cup" to close the first step, then begins "Put" with a capital letter to open the second. Both sentences are complete, and the separation is clean and correct. Choice B uses a comma instead of a period, which is not strong enough to separate two complete sentences this way. Joining two full sentences with only a comma is called a comma splice — a common mistake. Choice C places the period in the wrong spot, cutting off mid-thought after "put it," which leaves "On the shelf" as an incomplete sentence that doesn't make sense on its own. Choice D gets the period right but fails to capitalize "put," which is required whenever you start a brand-new sentence after a period. A simple tip to remember: every time you end a sentence with a period, the very next word must start with a capital letter — no exceptions. On questions like this, check two things together: (1) Is the period in the right place? and (2) Is the next word capitalized? Only when both are correct do you have a properly written new sentence.

Question 8

Read these four sentences from a note from the bank: (A) I called the bank after work. (B) The bank was open, so I spoke to Lee. (C) When Lee answered, I gave my name. (D) Lee checked my card, I checked the bill.

Which sentence is a run-on and needs correction?

  1. I called the bank after work.
  2. The bank was open, so I spoke to Lee.
  3. When Lee answered, I gave my name.
  4. Lee checked my card, I checked the bill. (correct answer)
Explanation: When checking sentences for errors, one of the most important things to look for is whether two complete thoughts are joined correctly. A run-on sentence happens when two independent clauses (complete thoughts that could each stand alone) are smashed together without proper punctuation or a connecting word. Sentence D — "Lee checked my card, I checked the bill" — is the run-on. It contains two complete thoughts: "Lee checked my card" and "I checked the bill." These are joined with only a comma, which isn't strong enough to hold two full sentences together. This common mistake even has a name: a comma splice. To fix it, you could add a conjunction ("Lee checked my card, and I checked the bill"), use a semicolon ("Lee checked my card*;* I checked the bill"), or split it into two sentences. The other choices are all correctly written. Sentence A — "I called the bank after work" — is one complete thought with no joining problem. Sentence B — "The bank was open, so I spoke to Lee" — uses a comma plus the word "so" to correctly connect two ideas; that's the right way to do it. Sentence C — "When Lee answered, I gave my name" — starts with a dependent clause ("When Lee answered"), which correctly leans on the main clause that follows, making it one proper sentence. A good tip to remember: a comma alone is never enough to join two complete sentences. If you can split the sentence at the comma and both halves stand alone, you likely have a run-on that needs a fix.

Question 9

Is the clinic open today I need to pick up my pills.

Which choice uses the correct punctuation?

  1. Is the clinic open today. I need to pick up my pills.
  2. Is the clinic open today, I need to pick up my pills.
  3. Is the clinic open today I need to pick up my pills?
  4. Is the clinic open today? I need to pick up my pills. (correct answer)
Explanation: When a sentence asks a question, it needs a question mark at the end — and when two separate thoughts appear together, each one needs its own ending punctuation. That's exactly what this question is testing. The sentence has two distinct ideas: a question ("Is the clinic open today?") and a statement ("I need to pick up my pills."). Each one is a complete thought, so each one needs its own punctuation mark. Choice D handles this perfectly — the question gets a question mark, and the statement gets a period. This is the correct answer. Choice A puts a period after the question, which is wrong. A period signals a statement, but "Is the clinic open today" is clearly a question. Ending it with a period makes the punctuation misleading. Choice B uses a comma between the two thoughts, which creates what's called a comma splice — two complete sentences joined with just a comma. A comma isn't strong enough to separate two full ideas; you need proper end punctuation for each. Choice C puts the question mark at the very end, after both sentences. This makes it look like the whole thing is one question, but "I need to pick up my pills" is not a question — it's a statement. Putting a question mark after it is incorrect. A handy tip: whenever you see a sentence that starts with a question word like is, are, can, do, or did, it almost certainly needs a question mark — not a period or comma. Train yourself to spot question words at the beginning of a sentence as a signal to look for that question mark.

Question 10

The fee is $5.50 you can pay at the desk.

Which choice correctly ends the first sentence after the price?

  1. The fee is $5.50. You can pay at the desk. (correct answer)
  2. The fee is $5.50, you can pay at the desk.
  3. The fee is $5.50 you can pay. At the desk.
  4. The fee is $5.50. you can pay at the desk.
Explanation: When two complete thoughts are written together without proper separation, you get what's called a run-on sentence. Your job here is to find the punctuation that correctly splits "The fee is $5.50" and "You can pay at the desk" into two separate, complete sentences. Choice A is correct. Placing a period after "$5.50" ends the first sentence cleanly, and capitalizing "You" signals the start of a brand-new sentence. Both thoughts are complete and properly separated — this is exactly how a run-on gets fixed. Choice B uses a comma between the two complete thoughts, which creates what's called a comma splice — a very common error. A comma alone isn't strong enough to separate two full sentences. You need a period, semicolon, or a connecting word like "and." Choice C breaks the sentence in the wrong place entirely. "The fee is $5.50 you can pay" runs two ideas together without separation, and then "At the desk" is left as a fragment — an incomplete thought that can't stand alone as a sentence. Choice D places a period in the right spot but fails to capitalize the word "you" that follows. In standard writing, the first word of every new sentence must be capitalized. This makes D incorrect even though the period itself is in the right place. A quick tip to remember: whenever you see two complete thoughts bumping into each other, ask yourself — does this need a period and a capital letter? That simple check will help you catch run-ons and comma splices every time.
