Question

Fill in the blank with the best possible option:
Metals such _____ Iron and Copper are very useful.

• A. that
• B. as
• C. if
• D. or

Answer 1

The correct option is B as

The given sentence is about different types of metals. To introduce the examples or the types of a particular banner, we pair 'as' with 'such' and create the idiom or phrase 'such as'. Iron and Copper are examples of useful metals. Hence option B is correct. 'That' when paired with 'such' refers to an extent of something as in 'It was such an interesting story that I finished reading it in one sitting'. It does not refer to an example. Hence, option A is incorrect. 'If' refers to a condition, a hypothetical situation that may or may not be true as in 'I'll go if you come with me'. There isn't any hypothetical situation here, and 'if' doesn't pair up with 'such' as they have different meanings, hence option C is incorrect. 'Or' is used to present a choice between two things 'this or that'. There isn't a choice between the hobbies in this sentence, hence it can't be paired with 'such' and option D is incorrect.
