Select the most appropriate option to fill in blank number 1.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. use of.
Context: The sentence talks about the role of traditional medicines and the first blank needs a phrase showing that they make 'use of' natural products. 'Traditional medicines make ___ natural products' means that they utilise them.
Analysis of the given options:
-
used off – Incorrect phrase and wrong preposition
-
use of – Correct phrase meaning “utilise”
-
uses of – Incorrect here because the structure “make uses of” is grammatically wrong; it should be “make use of”
-
used of – Grammatically incorrect combination
Correct word: use of
Reason: The idiomatic expression is “make use of” meaning to utilise.
Hence, the chosen option is correct.
