Answer:
Question 11:
The correct answer is (d) The new company, which makes computers, has not yet turned a profit.
Explanation: This sentence uses the correct subject-verb agreement and punctuation. The relative clause "which makes computers" is set off by commas, providing additional information about the company. The verb "has" agrees with the singular subject "company."
Question 12:
The correct answer is (c) She and her family live in Wyoming, and she rides horses six days a week.
Explanation: This sentence uses the correct subject-verb agreement and conjunction. The verb "live" agrees with the plural subject "She and her family." The conjunction "and" connects the two actions, indicating that both living in Wyoming and riding horses are happening.
Question 13:
The correct answer is (d) The store manager ordered 20 pounds of chocolate, however, she expected to sell only 80 percent of it.
Explanation: This sentence is grammatically incorrect. The use of "however" creates a comma splice, where two independent clauses are incorrectly joined by a comma. To correct this, a coordinating conjunction or a semicolon should be used to connect the clauses.
Question 14:
The correct answer is (c) No permanent work is available; moreover, the money earned by picking crops is not enough to feed the family.
Explanation: This sentence uses the correct punctuation and conjunctions. The semicolon is used to separate two related but independent clauses. The conjunctive adverb "moreover" is correctly used to add information and show a logical relationship between the two clauses.
Question 15:
The correct answer is (c) There is a parking spot behind their Winnebago.
Explanation: This sentence is grammatically incorrect. The word "there" is used incorrectly instead of the possessive pronoun "their." The correct sentence should use "their" to show possession.
Question 16:
The correct answer is (a) As we get older, our bodies need fewer hours of sleep.
Explanation: This sentence does not contain a usage error. It uses the correct verb form "need" to agree with the plural subject "our bodies." The comparison of needing fewer hours of sleep as we get older is also logical and appropriate.
Question 17:
The correct answer is (d) Thomas Jefferson's great collection of books eventually became the Library of Congress.
Explanation: This sentence has correct punctuation. The possessive form "Thomas Jefferson's" is used correctly to indicate possession. The sentence is clear and concise.
Question 18:
The correct answer is (c) Each day's menu features a different European country's cuisine.
Explanation: This sentence is grammatically incorrect. The possessive form "European countries" should be followed by the possessive form "cuisine" to show possession. The correct sentence should use the possessive form "European country's cuisine."
Question 19:
The correct answer is (a) My sister still lives at our parents' house.
Explanation: This sentence is grammatically incorrect. The possessive form "parents" should be plural and followed by an apostrophe to indicate possession. The correct sentence should use "parents'" to show that the house belongs to both parents.
Question 20:
The correct answer is (a) it's.
Explanation: This sentence uses the incorrect spelling of the possessive pronoun "it's." The correct spelling for the possessive pronoun is "its," without an apostrophe. "It's" is a contraction for "it is" or "it has."
