Question

Perseverance is important for success because __________.

• A. it is a form of gasoline
• B. it is the engine of success
• C. it keeps you motivated
• D. it gives you rest

Answer 1

The correct option is C it keeps you motivated

The first few lines draw a parallel between perseverance and gasoline. "Perseverance is about as important to achievement as gasoline is to driving a car." This sentence means that perseverance keeps you going on in life, if you want to achieve something. In other words, perseverance motivates a person. Without motivation, "you won't even be able to start your engine" (your aspirations, goals)
Option C: These words are implied by the quoted lines mentioned above. Hence C is correct.
Option A: Perseverance is not a form of gasoline. The passage draws a metaphor and does not provide a literal meaning. Also, perseverance is abstract whereas gasoline is a concrete, physical thing. Hence A is incorrect.
Option B: These words 'it is the engine of success' are metaphorical, but the passage already draws a metaphor. In comparison, the literal meaning, that 'it keeps you motivated' is preferred here. Hence B is incorrect.
Option D: These words are not implied by the passage. Hence D is incorrect.
