Select the most appropriate option to fill in blank no. 5.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. a.
Context: The sentence requires an indefinite article before the word “collective effort” because it is a singular, countable noun being introduced for the first time.
Meaning of the words:
the: definite article, refers to something specific
an: indefinite article used before vowel sounds
a: indefinite article used before consonant sounds
No article required: not suitable here
Correct word: a
Reason: “Collective effort” is singular and nonspecific; hence, the indefinite article ‘a’ is appropriate.
Final Sentence: Addressing plastic usage requires a collective effort to adopt more eco-friendly practices, support recycling initiatives, and invest in innovative materials that minimize environmental impact.
Hence, the chosen option will be correct.
