Select the most appropriate option to fill in blank number 2.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. When.
Context: The sentence is referring to a time-based condition - what will happen as obese children grow up. The blank needs a word that introduces this time-dependent clause.
Correct word: When
Reason: The structure of the sentence clearly needs a time conjunction to show the relationship between children growing up and the health issues they face later.
Hence, the chosen option will be correct.
