Question

4
read this sentence from the passage.
when parent sunflowers were planted in the desert, they failed to survive.
based on this statement, what is the author suggesting?
a. hybrid species will be wiped out by lack of adaptation in several years.
b. parent species may be less able to adapt than their hybrid offspring.
c. parent species will be unable to adapt after their offspring are born.
d. hybrids are born without the ability to adapt to the parents conditions.

Explanation:

• Analyze Option A: The sentence is about parent sunflowers in the desert, not hybrid species' future extinction, so A is incorrect.
• Analyze Option B: The parent sunflowers failed to survive in the desert. This implies that if hybrid offspring exist (the context of comparing with parents is implied in such questions), the parents may have less adaptability than hybrids, so B is reasonable.
• Analyze Option C: The sentence is about parents' survival in the desert, not about their adaptability after offspring are born, so C is incorrect.
• Analyze Option D: The sentence doesn't discuss hybrids' ability to adapt to parents' conditions, so D is incorrect.

Answer:

B. Parent species may be less able to adapt than their hybrid offspring.
