Select the most appropriate option to fill in blank no. 1.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. several.
"Several" fits the context as it refers to a number of years. The phrase "several years ago" is commonly used to indicate an unspecified but relatively small number of years.
"Particular" and "enormous" do not fit the context of referring to a number of years.
"Immense" suggests something very large or significant in size or extent, which is not suitable for describing a time frame.
Thus, "several" is the most appropriate choice.
