Question
Find out which word can be filled up in the blanks in
sentence in the same sequence to make the sentence grammatically correct and meaningfully complete. Ritwik has been writing a book ā¦ā¦ā¦.. three daysSolution
Option (2) uses āsinceā which is used to indicate a starting point from which an ongoing action has begun and not a duration as used in the sentence. Option (3) uses ā fromā which is also used to indicate a starting point and not a duration as used in the sentence.Ā Option (1) rightly uses āforā to indicate an entire time duration ā 3 days.
