Question
The transition by online classes (A)/to offline
education was smooth (B)/for the much part, (C)/ with teachers and students (D)/adapting at COVID-19 safety protocols (E). In each of the questions, a sentence is divided into five parts namely A, B, C, D and E. In which one of the parts is given in bold and is grammatically and contextually correct. You have to identify which fragment, apart from the bold one, is correct in terms of grammar and usage.Solution
1- the preposition ‘by’ should be replaced with ‘from’. 3- ‘much’ should be replaced with ‘most’. 4- the preposition ‘at’ should be changed to ‘to’. The transition from online classes to offline education was smooth for the most part, with teachers and students adapting to COVID-19 safety protocols.
