Praxis Core Revision in Context Summary

Sentence 5 says most plants grew well; sentence 6 describes plants that did not. That is a contrast, so "However" is the right transition.

Wrong choices

• "Therefore,": "Therefore" shows a result, but wilting is not a result of plants growing well.
• "For example,": "For example" would introduce an example of plants growing well.
• "Similarly,": "Similarly" shows likeness, but the ideas are opposite.
• "As a result,": "As a result" shows cause and effect, which does not fit.

The paragraph is about the students' garden project. When the cafeteria was built has nothing to do with the garden, so sentence 4 should be removed.

Wrong choices

• "Sentence 5": Sentence 5 reports how the garden grew, which is on topic.
• "Sentence 6": Sentence 6 gives a problem the students had with the garden.
• "Sentence 7": Sentence 7 sums up the project.
• "Sentence 8": Sentence 8 tells what will happen next, which closes the paragraph.

The letter's purpose, stated in sentence 1, is to ask for Sunday hours to return. A good conclusion repeats that request and ties it to the reasons given.

Wrong choices

• "The library also has a large collection of mystery novels.": The mystery collection is a new detail that does not support the request.
• "Some people prefer to read e-books at home.": This works against the letter's argument and does not conclude it.
• "Story time is usually held in the children's room.": This is a minor detail, not a conclusion.
• "The library was first built many years ago.": The library's age is unrelated to the request.

The paragraph is about teenagers' sleep and later school start times. A swimming pool has nothing to do with sleep, and it also separates sentence 8 from the idea it refers to.

Wrong choices

• "Sentence 2": Sentence 2 gives the recommended amount of sleep, which supports the topic.
• "Sentence 4": Sentence 4 explains a problem caused by lack of sleep.
• "Sentence 6": Sentence 6 introduces the solution the paragraph recommends.
• "Sentence 8": Sentence 8 gives the writer's recommendation, the paragraph's goal.

The teachers want to repeat the project because it succeeded. A comma plus "so" joins the two complete sentences and shows cause and effect.

Wrong choices

• "The project was a success, teachers plan to repeat it next year.": Two complete sentences joined only by a comma form a comma splice.
• "The project was a success, although teachers plan to repeat it next year.": "Although" shows contrast, but there is no contrast here.
• "Being a success, teachers plan to repeat the project next year.": This says the teachers were a success (a dangling modifier).
• "The project, which teachers plan to repeat next year because it was a success.": This has no main verb, so it is a fragment.

The letter is formal and polite, and it supports its request with facts. The best revision explains the effect of the cut without insulting the council.

Wrong choices

• "Cutting Sunday hours was a really bad idea, to be honest.": "Really bad idea, to be honest" is too casual for a formal letter.
• "The council messed up big time when it cut Sunday hours.": "Messed up big time" is slang.
• "Anyone can see that cutting Sunday hours was foolish.": Calling the decision "foolish" insults the readers the letter is trying to persuade.
• "Who in their right mind would cut Sunday hours?": A sarcastic question is rude and does not give a reason.

Both sentences have the same subject (lack of sleep), so they can share it: "can make ... and can also affect." The result is correct and concise.

Wrong choices

• "Lack of sleep can make it hard to pay attention in class, it can also affect mood and memory.": This is a comma splice.
• "Lack of sleep, which can make it hard to pay attention in class and also affect mood and memory.": This has no main verb, so it is a fragment.
• "Although lack of sleep can make it hard to pay attention in class, it can also affect mood and memory.": "Although" shows contrast, but both ideas are harmful effects.
• "Lack of sleep can make it hard to pay attention in class; and it can also affect mood and memory.": A semicolon should not be followed by "and" when joining two simple sentences like these.

The new sentence explains why "working parents" needed Sunday hours, and "them" must point back to those parents. That only works right after sentence 3.

Wrong choices

• "After sentence 1": After sentence 1 there are no people for "them" to refer to.
• "After sentence 2": After sentence 2, "them" would have no clear reference.
• "After sentence 4": After sentence 4, "them" would refer to the students, who are not described as working.
• "After sentence 6": After sentence 6, the sentence would interrupt the move to the conclusion and "them" would be unclear.

The paragraph argues that a later start can help students who lack sleep. The best sentence links the later start to more sleep and to the recommendation in sentence 2.

Wrong choices

• "Some students prefer to study late at night with their friends.": Studying late with friends does not explain how later start times help.
• "Many schools also serve breakfast before classes begin.": Breakfast is a different topic.
• "Starting classes later is the only way to solve every problem in schools.": "The only way to solve every problem" is an overstatement the paragraph cannot support.
• "School buses are expensive to run in some districts.": Bus costs are off topic and do not explain the benefit.
