and Detailed Explanations for Optimal Test Readiness
SECTION 1: ENGLISH TEST (Questions 1–38)
Passage Context (Questions 1–5): The following passage is adapted from a student essay about
renewable energy adoption.
The transition to renewable energy sources represents one of the most significant challenges of
the twenty-first century. (1) Many nations have committed to reducing their carbon emissions,
but the path to a sustainable energy future remains fraught with obstacles. The intermittent
nature of solar and wind power, for instance, creates significant challenges for grid stability.
(2) Energy storage technologies, such as advanced battery systems, are therefore essential to
the widespread adoption of renewables. However, these technologies (3) remain expensive and
are not yet scalable to meet global demand. Some critics argue that nuclear power, (4) which
produces no direct carbon emissions, should play a larger role in the transition. Proponents of
renewables counter (5) that nuclear waste and safety concerns present unacceptable risks.
,Question 1
Which choice most effectively combines the underlined sentences while maintaining clarity and
meaning?
A) Many nations have committed to reducing their carbon emissions, however, the path to a
sustainable energy future remains fraught with obstacles.
B) Many nations have committed to reducing their carbon emissions, but the path to a
sustainable energy future remains fraught with obstacles.
C) Many nations have committed to reducing their carbon emissions; the path to a sustainable
energy future remains fraught with obstacles.
D) The path to a sustainable energy future remains fraught with obstacles even though many
nations have committed to reducing their carbon emissions.
Correct Answer: B
Rationale: Option B uses the coordinating conjunction "but" to create a clear contrast between
the commitment and the obstacles, maintaining the original meaning with proper punctuation.
Option A creates a comma splice; C lacks the contrastive element; D is grammatically correct but
less direct and changes the emphasis.
Question 2
The writer is considering deleting the underlined sentence at (2). Should it be kept or deleted?
A) Kept, because it provides essential context for understanding the challenge described.
B) Kept, because it offers a specific solution to the problem of intermittency.
C) Deleted, because it introduces a tangent unrelated to the main argument.
D) Deleted, because it repeats information stated elsewhere in the passage.
Correct Answer: B
Rationale: The sentence introduces energy storage as a solution to the intermittency problem
mentioned in the previous sentence. This is essential explanatory content that advances the
argument.
Question 3
A) NO CHANGE
B) is remaining
C) remains
D) remained
,Correct Answer: C
Rationale: "Remains" is the correct present tense form indicating a current state. The passage
uses present tense throughout to discuss the current situation.
Question 4
A) NO CHANGE
B) which produces no direct carbon emissions
C) that produces no direct carbon emissions
D) producing no direct carbon emissions
Correct Answer: A
Rationale: The clause is nonrestrictive (provides additional information) and is correctly set off
by commas. "Which" is the appropriate relative pronoun for nonrestrictive clauses.
Question 5
A) NO CHANGE
B) that nuclear waste and safety concerns presented unacceptable risks.
C) that nuclear waste and safety concerns present unacceptable risks.
D) nuclear waste and safety concerns present unacceptable risks.
Correct Answer: A
Rationale: The original is grammatically correct: the verb "counter" requires a "that" clause, and
"present" is the correct present tense form. Option B changes to past tense unnecessarily; C is
missing the required "that"; D is a comma splice.
Question 6
Which of the following alternatives to the underlined portion would be LEAST acceptable?
The CEO's decision was predicated upon the assumption that market conditions would improve.
A) based on
B) contingent on
C) dependent on
D) contrary to
, Correct Answer: D
Rationale: "Predicated upon" means "based on." Options A, B, and C are synonyms. "Contrary
to" means the opposite and would change the meaning entirely.
Question 7
The researchers were disinterested in the commercial applications of their discovery.
A) NO CHANGE
B) uninterested
C) disinterestedly
D) uninterestingly
Correct Answer: B
Rationale: "Uninterested" means not interested; "disinterested" means impartial or unbiased.
The context indicates the researchers lacked interest, so "uninterested" is correct.
Question 8
Neither the manager nor the employees was satisfied with the new policy.
A) NO CHANGE
B) were
C) have been
D) is
Correct Answer: B
Rationale: With "neither...nor," the verb agrees with the noun closest to it. "Employees" is
plural, so "were" is correct.
Question 9
The professor's lecture, which lasted for three hours, was exhausting for the students.
Which of the following true statements about the underlined portion is correct?
A) It is a restrictive clause essential to identifying the lecture.
B) It is a nonrestrictive clause providing additional information.
C) It is a participial phrase modifying "professor."
D) It is an appositive renaming "lecture."
