Question

The Arctic tern is known ____(3)____ make an annual journey of 22,000 miles.

• A. to
• B. by
• C. with
• D. as

Answer 1

The correct option is A to

In the given sentence the preposition used should be decided based on what it means when placed between the two words ‘known’ and ‘make’. The phrase ‘known to’ means that it is recognized as something within the scope of knowledge. Since the idea expressed here is a fact and understood by many, ‘to’ is an apt answer. Hence option A is correct. Whereas ‘known by’ would be unsuitable in the given context, since it speaks about a movement and not another name, also here the sentence is not about the bird being ‘known by’ a group of people. Thus option B is incorrect. Similarly ‘with’ cannot be used either, since ‘with’ is commonly used to denote a tool, and the same would not be grammatically relevant here. Therefore option C is incorrect. Whereas ‘as’ is used along with ‘known’ when we wish to convey another name or idea which is not the case here. Hence option D is incorrect
