Q:

Read each sentence to find out whether there is an error in it. The error, if any, will be in one part of the sentence. If there is no error, the answer will be “No Error”.

A) Linking traditional American Native stories B) to historic records of a Japanese tsunami
C) was considered an exception, not the start D) of a fruitful geological collaboration.
 
Answer & Explanation Answer: A) Linking traditional American Native stories

Explanation:

In 1 part, use of 'Native' after ‘American’ is incorrect. Also ‘traditional’ should come before ‘stories’. Native is an adjective that is used here for American and not stories. So native will come before American. Traditional is used as an adjective for stories. This is a case of misplaced modifiers.Hence 1 is the correct choice.

Q:

Read each sentence to find out whether there is any error in any underlined part and indicate your response in the Answer Sheet against the corresponding letter i.e., (a) or (b) or (c). If you find no error, your response should be indicated as (d).

A) All the boys B) returned back home
C) well in time for lunch. D) No error
 
Answer & Explanation Answer: B) returned back home

Explanation:

Error is in second part. Returning means coming back to place from where you began. So, the use of back after returned becomes redundant. Without using back, the meaning remains the same. We can omit ‘back’ in part b, and use ‘returned home.’
