Reading Comprehension & Vocabulary (Questions 1–20)
Reading Comprehension
1.
Read the following excerpt:
,"Although renewable energy sources like solar and wind are sustainable, their intermittent nature
requires significant investment in energy storage solutions to ensure grid reliability."
What is the primary concern expressed in the excerpt?
A. The high cost of solar panels
B. The inefficiency of wind turbines
C. The variability of renewable energy output
D. The environmental impact of battery production
C. The variability of renewable energy output
The excerpt emphasizes that solar and wind energy are "intermittent," meaning their output
varies with weather and time. This variability necessitates storage solutions for consistent power
supply. Options A, B, and D are not mentioned as the primary concern.
Vocabulary in Context
2.
In the sentence, "Her acerbic remarks during the debate alienated even her supporters," the word
acerbic most nearly means:
A. witty
B. sarcastic
C. bitter or sharp
D. enthusiastic
C. bitter or sharp
"Acerbic" describes tone or language that is sharp, caustic, or biting—often unpleasantly so. While
sarcasm (B) can be acerbic, the core meaning is bitterness or sharpness. Witty (A) and
enthusiastic (D) are positive and do not fit the negative consequence described ("alienated").
,Reading Comprehension
3.
Which best summarizes the main idea of the following paragraph?
Urban green spaces, such as parks and community gardens, offer more than aesthetic value. Research
indicates they reduce stress levels, encourage physical activity, and foster social cohesion among
residents. Cities investing in such infrastructure often see long-term public health benefits.
A. Parks are expensive to maintain.
B. Green spaces improve urban well-being.
C. Community gardens are more useful than parks.
D. Urban planning ignores mental health.
B. Green spaces improve urban well-being.
The paragraph explicitly links green spaces to stress reduction, physical activity, social cohesion,
and public health—collectively describing improved well-being. Other options are either
unsupported (A, C, D) or distort the focus.
Vocabulary
4.
Choose the word that is most nearly opposite in meaning to ephemeral:
A. fleeting
B. temporary
C. enduring
D. fragile
C. enduring
, "Ephemeral" means lasting for a very short time. Its antonym is "enduring," which means lasting
over a long period. Options A and B are synonyms of "ephemeral"; D is unrelated.
Reading Inference
5.
A passage states: "Despite meticulous planning, the expedition failed due to unanticipated weather
patterns." What can be reasonably inferred?
A. The team did not prepare adequately.
B. Weather was the decisive factor in the failure.
C. The planners ignored climate data.
D. Future expeditions will succeed.
B. Weather was the decisive factor in the failure.
The word "despite" indicates planning was thorough ("meticulous"), yet failure occurred because
of "unanticipated weather"—making weather the key cause. A and C contradict the description of
planning; D is speculative.
Reading Comprehension
6.
What is the author’s purpose in the following sentence? "Every citizen must recognize that voting is
not merely a right but a civic responsibility."
A. To inform about election procedures
