Select the most appropriate option that can substitute the underlined segment in the given sentence.
Research in Social Sciences is plagued nowadays on gloomy definitions and measurements.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. nowadays by gloomy definitions.
'Plagued by' is the correct phrase here, meaning affected or troubled by something.
In this case, the research is troubled or influenced by gloomy definitions and measurements.
'By' is the correct preposition to indicate the source or cause of the problem.
The other options:
'Amid' refers to being surrounded by something, which is not appropriate in this context.
'Onto' and 'during' do not fit here, as they don’t convey the meaning of being affected by or troubled by something.
Thus, 'plagued by' is the most fitting expression, making Option En2 the correct choice.
