The question asks us to identify the incorrect sentences from the given options. Let's examine each sentence to understand the grammatical correctness:
Based on the analysis above, the incorrect sentences are 1 and 5. Therefore, the option "1,5" is the correct answer.
To determine which sentences are incorrect, let's analyze each one:
"The boss accused her employee for stealing information."
The correct preposition to use with "accuse" is "of," not "for." Thus, it should be: "The boss accused her employee of stealing information."
"The boss had better discuss the issue with the employee concerned."
This sentence is structurally and grammatically correct. "Had better" is correctly used to suggest that it would be good or necessary for the boss to take this action.
"The India of 2022 is very different from the India of 1947."
This sentence is correct. It effectively compares India in two different years using the appropriate construction.
"The government is committed to providing people with food."
This sentence is grammatically correct and clearly conveys the government's commitment.
"He is good in playing the piano."
The correct preposition here should be "at," not "in." Thus, it should be: "He is good at playing the piano."
Based on the above analysis, sentences 1 and 5 have grammatical errors. Thus, the option with incorrect sentences is 1,5.
