Select the most appropriate option to fill in blank no. 1.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. during.
Context: The line is: “…alcohol use by women (1) ______ pregnancy was the cause of physical and mental birth defects …”
The missing word must show the time period when alcohol was consumed.
Meaning of the words:
-
On = shows a specific day/date (not suitable).
-
About = means concerning (doesn’t show time).
-
Along = means together with (not correct here).
-
During = shows something happening within a time period (correct).
Correct word: The correct word is during.
Reason: The correct phrase is “during pregnancy”, because it describes alcohol use happening within the period of pregnancy.
Final Sentence: “In 1981, the US Surgeon General issued a public health warning that alcohol use by women during pregnancy was the cause of physical and mental birth defects in children.”
Hence, the chosen option will be correct.
