Which of the following sentences has correct subject-verb agreement?

The main idea of the paragraph explains how George Washington retired from public life but later returned to help create the Constitution. Option A provides additional detail about his personal plans as a private citizen, but it does not contribute directly to the main narrative about his retirement and return to public service. Therefore, removing it would have the least impact on the paragraph’s overall meaning.

Option B is important because it explains that Washington intended his retirement to be permanent, which helps explain why his later return to public life was significant. Option C is essential because Shays’ Rebellion was a major historical event that helped lead to the Constitutional Convention. Option D is crucial because it introduces the main topic of Washington’s retirement, which the rest of the paragraph discusses.

The suffix “-hood” refers to a state, condition, or period of life. For example, words like adulthood and neighborhood use the suffix to describe a state or condition. Therefore, childhood means the state or period of being a child, which makes it the correct answer.

Option A is incorrect because childlike means having qualities similar to a child, not the state of being one. Option B is incorrect because children is simply the plural form of child. Option C is incorrect because childish describes behavior that is immature or silly, not the state of being a child.

Option C is correct because the introductory participial phrase clearly describes the subject of the sentence. The phrase “Wearing a warm coat” logically refers to “I,” the person who walked to the store. Because the modifier clearly describes the subject performing the action, the sentence is grammatically correct.

Option A is incorrect because it creates a dangling modifier. The phrase “Killing myself all day” suggests that the yard performed the action, which is illogical and grammatically incorrect. Option B is incorrect because the phrase “looking for my hat” is unclear; it seems to suggest that the shoe was looking for the hat instead of the person. Option D is incorrect because “standing on the shore” appears to describe storm clouds, which is illogical. The modifier should clearly describe the person observing the clouds.

A dangling or misplaced modifier occurs when a descriptive phrase is placed in the wrong part of the sentence, making it unclear what the phrase is describing. In option B, the phrase “that needed paint” appears to describe the garage, because it comes immediately after the word garage. However, logically the sentence likely means that the truck needed paint, not the garage. Because the modifier is not clearly connected to the correct noun, the sentence creates confusion and becomes a dangling or misplaced modifier.

Option A is incorrect because the phrase “who is studying or reading” clearly describes anyone, so there is no confusion about the modifier. Option C is also incorrect because “sleeping” clearly describes the young child, and “contented” clearly describes the puppy, so all modifiers are correctly placed. Option D is incorrect because the word “outdated” clearly modifies driving law, and the sentence does not contain a misplaced modifier.

The word “retrograde” means moving backward, returning to an earlier or less advanced state, or resisting progress. In the sentence, the phrase “retrograde times” suggests that the period being described is one in which society or thinking has moved backward rather than forward. Because backward closely matches this meaning, it is the best synonym.

Option B is incorrect because progressive means moving forward or improving, which is the opposite meaning of retrograde. Option C is incorrect because unexplained refers to something that has not been clarified or understood, which is unrelated to the idea of moving backward. Option D is incorrect because “musary” is not a standard English word and does not match the meaning of retrograde.

Formal writing is best described as professional. It uses clear, structured language and avoids slang, contractions, and overly casual expressions. Formal writing is commonly used in academic papers, research reports, professional documents, and official communications.

Option A is incorrect because casual describes informal communication, such as everyday conversation or personal messages. Option B is incorrect because spontaneous suggests something that is done quickly without preparation, whereas formal writing is usually carefully planned and edited. Option D is incorrect because passionate describes strong emotion, which may appear in writing but does not define the structured and professional style of formal writing.

The correct spelling is occurrence, which contains two c's and two r's. This word is commonly used to describe an event or something that happens.

Option B is incorrect because reccommend contains an extra c. The correct spelling is recommend. Option C is incorrect because comittee is missing a letter; the correct spelling is committee, which contains two m's and two t's. Option D is incorrect because tommorrow contains too many letters. The correct spelling is tomorrow, with two r's and one m.

Option A is correct because all the words in the sentence are spelled correctly. Words such as Alejandro, weekend, community, and centers are properly spelled, and the sentence contains no spelling mistakes.

Option B is incorrect because the word “hear” is misspelled in this context. The correct word should be “here,” which refers to a location. The word “hear” means to perceive sound, which changes the meaning of the sentence and makes it incorrect.

Option C is incorrect because it contains two spelling errors. The word “harestyles” should be spelled “hairstyles,” and “hare” should be “hair.” A hare is an animal similar to a rabbit, so the incorrect spelling creates confusion in the sentence.

Option D is incorrect because the word “qestion” is misspelled. The correct spelling is “question.” Because of this spelling error, the sentence does not meet the requirement that all words be spelled correctly.

A complete sentence must contain a subject and a verb and express a complete thought. Option B includes the subject “Mr. Alvarez” and the verb “drove.” Even though the sentence is short, it still expresses a complete idea and is grammatically correct.

Option A is incorrect because “Into the mountains” is a prepositional phrase and does not contain a subject or verb. Option C is incorrect because “The car of Mr. Alvarez” is a noun phrase without a verb. Option D is incorrect because “Over the highway bridge” is also a prepositional phrase and does not express a complete thought.

A complete sentence must contain a subject, a verb, and a complete thought. In option C, the subject is “I”, the verb is “walked,” and the sentence expresses a complete idea. Therefore, it is a grammatically complete sentence.

Option A is incorrect because “Walking with a limp as a result of the thorn” is only a phrase and does not contain a clear subject performing the action. Option B is incorrect because it begins with “When,” which introduces a dependent clause and leaves the sentence incomplete. Option D is incorrect because “Running through the park before breakfast” is a participial phrase and does not form a complete sentence.
