* Here, the error lies in the second part of the sentence ‘to doing’.

* In the given sentence, persisted needs to be followed by preposition ‘in’. So, the grammatically correct sentence will be “She persisted in doing what she wanted despite opposition”.

* persist in (doing something) means to continue pursuing some action with steadfast or obstinate tenacity.

* Hence option A is the correct answer.

 The given sentence is grammatically incorrect, and the error lies in option C.

Here, the error is in phrase ‘my sister’.

Comparative adjectives compare one person or thing with another and enable us to say whether a person or thing has more or less of a particular quality.

We compare person with another person and things with another things.

o E.g. :- Josh is taller than his sister.

But, in the given sentence, comparison is not being done between houses.

Rather, it is between house and a person.

Thus, add ‘that of’ before ‘my sister’ to make the sentence grammatically correct.

The correct sentence should be :- My house is more spacious than that of my sister.

The sentence is grammatically incorrect, and the error lies in option A. The error is related to Preposition.

* “On” as a preposition is used when in or into a position covering, touching or forming a part of a surface.

* “In” as a preposition is used to show involved in something; taking part in something.

* The given sentence is conveying the meaning that “half the members” submitted their resignations as part of taking part in protest. Thus, usage of preposition “In” is appropriate here.

* Hence, “their resignations in protest” is the correct substitution.

Thus, the correct sentence will be:

At the last meeting which took place in November, half the members submitted their resignations in protest.

Hence, option A is the correct answer.

'Did you baked' is incorrect here.

Note that 'did' always takes the verb in its base form.

Thus, it should be 'Did you bake the cake yourself this time?'

The sentence is grammatically incorrect, and the error lies in option C. The error is related to Preposition.

• “Since” as preposition is used for point of time.

• “From” as preposition is used simply shows the origin of someone/something. It does not necessarily mean the point of time.

• For example:

He has been off work since Monday.

He received a letter from his brother.

• In the given sentence, “childhood” is a point of time when someone was a child. From the meaning of the sentence, it is clear that speaker needs a point of time in past to show the starting point for his fondness. Thus, “since” should be used in place of “from”

• Hence, “since childhood” is the correct substitution.

Thus, the correct sentence will be:

I never miss a cricket match as I am fond of cricket since childhood.

Hence, option C is the correct answer.

The sentence is grammatically incorrect, and the error lies in option B. The error is related to Tense.

• The use of the verb “win” for the singular subject “he” is erroneous.

• We use the present perfect i.e. “has/have + V3” to show the action done in a time period up to the present.

For example:

She has decided to focus her time on her business activities.

• We use the simple present tense to describe the habits or unchanging situations.

For example:

The sun rises in the east.

• In the given sentence, it is clear that we don’t need a sense of habit or unchanging situation i.e. “winning accolades” is not an unchanging situation. It is better to show the act of “win” as an action that has been done up to present time when such a sentence was mentioned/stated by someone. Thus, the present perfect form i.e. “has won” should be used.

• Hence, “has won” is the correct substitution.

Thus, the correct sentence will be:

He has won several accolades for his music compositions.

Hence, option B is the correct answer.

The given sentence is grammatically incorrect and the error lies in option D.

Here, the error lies in phrase ‘and punished’.

The given sentence is in passive form i.e. someone was late and due to that someone else punished.

So, we need a causative verb before ‘punished’ and that should be ‘get’.

We should use second form of the verb ‘get’ i.e. ‘got’

Thus, replace ‘and punished’ with ‘and got punished’ to make the sentence grammatically correct.

The correct sentence should be :- He was late for school and got punished.

The sentence is grammatically incorrect, and the error lies in option D. The error is related to Preposition.

• “For” as preposition is used for duration of time.

• “Since” as preposition is used for point of time.

• For example:

He has been off work since Monday.

They wandered about the city for an hour.

• The given sentence mentions “ten years” which is a time duration. Thus, preposition “for” should be used.

• Hence, “for ten years” is the correct substitution.

Thus, the correct sentence will be: They have lived in this apartment for ten years.

Hence, option D is the correct answer.

• Here, the error is related to adverb.

• In the given sentence, we need a word that tells us more about a noun and that word should be adjective not an adverb.
  
  
• Here, 'consideration' is a noun which means the act of thinking about something carefully.
  
  
• 'Carefully' is an adverb which means with great attention.
  
  
• 'Careful' is an adjective which means giving a lot of attention to what you are doing so that you do not have an accident, make a mistake, or damage something.
  
  
• Thus, replace 'carefully' with 'careful' to make the sentence grammatically correct.
  

The correct sentence is :- After careful consideration of your proposal, I regret to say that we are unable to accept it.

The given sentence is grammatically incorrect, and the error lies in option A.

Here, the error is of subject verb agreement.

The given sentence is in present perfect tense.

With singular subject ‘fisheries sector’, we use singular auxiliary verb i.e. ‘has’.

Thus, replace ‘have’ with ‘has’ to make the sentence grammatically correct.

The correct sentence should be :- The fisheries sector has grown significantly in the last one year.
