Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2, i.e., considered.
The sentence is stating a general opinion or belief about whales and dolphins. The correct word should mean “thought to be” or “regarded as.”
Considered – correctly means “regarded as” or “believed to be.”
Contemplated – means “thought deeply about” (not suitable here).
Maintained – means “claimed” or “asserted” (too strong for general belief).
Imagined – means “visualized” or “pictured in the mind” (not correct in this context).
Final Sentence: Whales and dolphins are considered to be very unusual creatures.
Conclusion: The most appropriate word to fill blank 1 is considered.
