Directions: In the following question, some part of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If a sentence is free from error, select 'No Error'.
1
Imported items are costlier (A) / then their (B) / domestic (C) / counterparts. (D) / No error (E) 
» Explain it
B
In part B, use of the adverb 'then' is absurd in the context and it, hence, must be replaced with the preposition 'than' that is commonly used while comparing two or more things. 

Hence, option B is correct.

 
2
These reports have (A) / deterred some (B) / women to have (C) / the operation. (D) / No error (E)
» Explain it
C
In part C, 'to have' should be replaced with 'from having' as 'deter', which is a verb, is generally followed by the preposition 'from' which has to be followed by a gerund.

The correct formation will be- "The reports have deterred some women to have the operation."

Hence, option C is correct.

 
3
It will be more better (A) / if one of the parents (B) / stays at home (C) / to look after the children. (D) / No error (E) 
» Explain it
A
In part A, the use of two comparatives 'more' and 'better' together is erroneous and hence 'more' can be replaced with 'much' to make it grammatically correct sentence.

Hence, option A is correct.

 
4
At my arrival (A) / in Delhi (B) / I went straight (C) / to the nearest hospital. (D) / No error (E)
» Explain it
A
In part A, the preposition 'at' must be replaced with 'on' to make it a grammatically correct sentence.

Hence, option A is correct.

 
5
I don't understand (A) / how she could (B) / treat him (C) / so bad.(D) / No error (E)
» Explain it
D
In part D, the adverb 'badly' must be used in place of the adjective 'bad' as an adverb is needed for the sentence to be grammatically correct. 

Hence, option D is correct.
