鏁寸瘒ip绛旀?ANSWERS AND EXPLANATIONS
Explanation for Correct Answer?A :
Choice (A) is correct.The sentence has a clear subject and verb,"she attended," and it properly organizes the rest of the information with the word "where."

Choice (B) is unsatisfactory because "[a]ttending Stanford University" and "where she met鈥?nd became鈥?n geology" are both dependent clauses.
Explanation for Incorrect Answer?C :
Choice (C) is unsatisfactory because it has no subject; the sentence consists of two dependent clauses.
Explanation for Incorrect Answer?D :

Explanation for Incorrect Answer?E :
Choice (E) is unsatisfactory because it joins two independent thoughts with only a comma.

ANSWERS AND EXPLANATIONS
Explanation for Correct Answer?D :
Choice (D) is correct.The word "that" properly connects the modifying clause "that would鈥?hip" to the independent clause "In the process鈥?rib," resulting in a clear and correct sentence.
Explanation for Incorrect Answer?A :
Choice (A) is unsatisfactory because it is illogical:it says that the purpose of Hoover designing the crib was for it to remain stable,not for her sons to have a place to sleep.
Explanation for Incorrect Answer?B :
Choice (B) is unsatisfactory because the stability of the crib was the key feature of its design; the two parts of the sentence should not be separated by "and."
Explanation for Incorrect Answer?C :
Choice (C) is unsatisfactory because the word "nevertheless" implies a contrast between the two clauses that does not exist in the sentence.
Explanation for Incorrect Answer?E :
Choice (E) is unsatisfactory because it unnecessarily repeats the word "designed."
32
ANSWERS AND EXPLANATIONS
Explanation for Correct Answer?D :
Choice (D) is correct.The writer's intention is to praise Hoover,and the second paragraph is essentially a list of her accomplishments,so it makes sense in the paragraph's concluding sentence for the writer to reiterate that these details show what a "remarkable woman" Hoover was.
Explanation for Incorrect Answer?A :
Choice (A) is unsatisfactory because it makes an illogical link with the preceding sentence:it makes no sense to state that Hoover designed a crib "because as a child she had learned several languages."
Explanation for Incorrect Answer?B :
Choice (B) is unsatisfactory because it inappropriately switches verb tenses ("she was also learning and published").
Explanation for Incorrect Answer?C :
Choice (C) is unsatisfactory because it is unclear what time the phrase "[b]y this time" is referring to.
Explanation for Incorrect Answer?E :
Choice (E) is unsatisfactory because "[n]evertheless" implies a contrast between the achievement of designing a crib and the achievements of learning languages and publishing scholarly papers that is not supported by the passage.
33
ANSWERS AND EXPLANATIONS
Explanation for Correct Answer?A :
Choice (A) is correct.Changing "being" to "was" transforms the clause "Lou Hoover鈥?ersatile person" into the independent clause the sentence needs,and makes verb tenses consistent throughout the sentence.
Explanation for Incorrect Answer?B :
Choice (B) is unsatisfactory because it fails to address the fact that the original sentence consists of two dependent clauses.
Explanation for Incorrect Answer?C :
Choice (C) is unsatisfactory because the replacement of "she" with "Lou Hoover" creates a grammatically incorrect sentence that seems to compare Lou Hoover to herself.
Explanation for Incorrect Answer?D :
Choice (D) is unsatisfactory because the deletion of "she was" does not change the fact that the sentence lacks an independent clause.
Explanation for Incorrect Answer?E :
Choice (E) is unsatisfactory because,while "had been" is an adequate substitution to make in the second clause,the sentence still consists of two dependent clauses.
34
ANSWERS AND EXPLANATIONS
Explanation for Correct Answer?B :
Choice (B) is correct.The sentence is properly linked with the preceding sentences through the phrase "[i]n addition," and the relationship between the two clauses is accurately indicated with the word "when."
Explanation for Incorrect Answer?A :
Choice (A) is unsatisfactory because entertaining Jessie DePriest was the act that broke the racial barrier; the two parts of the sentence should not be separated by "and" as if they describe separate events.
Explanation for Incorrect Answer?C :
Choice (C) is unsatisfactory because it reflects an unnecessary shift in tenses from the rest of the passage.
Explanation for Incorrect Answer?D :
Choice (D) is unsatisfactory because the information in sentence 14 is not a consequence of the information in sentence 13.
Explanation for Incorrect Answer?E :
Choice (E) is unsatisfactory because it is illogical; this structure would only make sense if the clauses were reversed ("By entertaining Jessie DePriest鈥?he became the first person to鈥?).
35
ANSWERS AND EXPLANATIONS
Explanation for Correct Answer?B :
Choice (B) is correct.Every sentence of the passage (except for the first two) praises Hoover as an exceptionally gifted and active woman,so a concluding sentence summarizing Hoover's life in a positive way is appropriate and expected.
Explanation for Incorrect Answer?A :
Choice (A) is unsatisfactory because the passage does not discuss Hoover as "gracious" or "polished"; the focus of the passage is on Hoover's adventures and accomplishments.
Explanation for Incorrect Answer?C :
Choice (C) is unsatisfactory because the first mention of Hoover's personal papers should not come in the last sentence of a passage about her life.
Explanation for Incorrect Answer?D :
Choice (D) is unsatisfactory because it is not "obvious" that little is known about Hoover's early life.It is logical to assume that the writer knows a great deal about Hoover's early life,but the passage focuses on her accomplishments as an adult.
Explanation for Incorrect Answer?E :
Choice (E) is unsatisfactory because it makes no sense to say that historians are the only people who know the year and town of Hoover's birth.All readers of the passage now know this information.
