Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1, i.e., improved.
Context: The sentence discusses how students reacted positively to simpler science concepts, and the effect was seen in their academic results. So, the missing word must reflect positive academic progress.
Meaning of the words:
Improved: Became better; showed progress. (Correct – indicates better performance)
Reframed: Expressed differently or from another perspective. (Not related to performance)
Regained: Got back something that was lost. (Doesn’t fit the context)
Regretted: Felt sorrow or disappointment. (Negative tone – not suitable here)
Correct word: Improved
Reason: Since students were thrilled with how simple science became, the natural result would be that their performance became better, i.e., improved.
Final Sentence: Students were thrilled with how simple science became, and their performance improved, he adds.
Hence, the chosen option will be correct.
