Frequently Asked Questions

1. What are some tricks to spot errors in error detection questions?
Ans-> Some of the tricks are:

  • Check for simple grammatical errors like wrong use of tenses or subject-verb agreement. 
  • Check the prepositions in the next step, followed by adverbs.

2. What is meant by subject-verb agreement Error?

Ans-> In this type of error, the verb does not agree with the subject. A singular subject should have a singular verb, and a plural subject should have a plural verb. By taking care of this, we can easily spot the error. 

3. What are the steps to solve the error detection questions?

Ans-> The steps are as follows:-

Step 1. First, read the sentence carefully. Most of the time, errors can be identified by reading the sentence carefully, especially the subject-verb agreement error.

Step 2. Check all the spellings. The error can be in that too.

Step 3. Read each part of the sentence carefully to spot the error.
