Hence, option A is the correct answer.

* The given sentence is a conditional sentence.

* The part “if you eat all that food” is the result that depends on the action stated before it.

* This is a first conditional sentence. It refers to a possible condition and its probable result.

* To make a sentence in the first conditional, we use, If + present simple, will/won't + verb.

* Thus, replace “are” with “will be”.

The correct sentence will be: You will be ill if you eat all that food.

Hence, option B is the correct answer.

The underlined part is grammatically incorrect. 

• Before the noun "workforce", we need an adjective. 
  
  
• Thus, in place of the noun "skill", use "skilled". 
  
  
• The use of the preposition "of" with the adjective "capable" is correct. 

The underlined part is grammatically incorrect.

* We use the future tense to predict something that will happen in the future.

* The given sentence talks about a general situation that happens with everyone.

* Thus, we will use the simple present tense in the underlined part.

* For the plural subject “indirect questions”, we will use the verb “are”, followed by V3.

* After the conjunction “while”, we will use the gerund “seeking”.

The correct sentence will be: Indirect questions are used while seeking information about an embarrassing subject.

Hence, option D is the correct answer.

Hence, option B is the correct answer.

* The use of the time phrase “last Sunday”, we can conclude that the given sentence is of the simple past tense.

* Thus, we will use the verb in the V2 form in the underlined part.

* Replace “I returning home” with “I returned home”.

The correct sentence will be: Last Sunday I returned home late at night.

Hence, option B is the correct answer.

* The sentence is in the simple past tense (as suggested by the use of “was”).

* Thus, the use of the modal “cannot” is erroneous. It should be replaced with “could not” (the past form).

* Also, the phrase “cannot help something” is used for saying that someone cannot stop themselves doing something

e.g. She couldn’t help laughing when she saw it.

* Thus, after “help”, use the present participle “laughing”.

The correct sentence will be: It was such a funny story that we couldn’t help laughing.

Hence, option D is the correct answer.

* The verb “say” or “said” is followed by the preposition “to” and “object”.

* In the underlined part, the preposition “to” is missing.

* The use of “would” in the latter part of the sentence suggests that the given sentence is in the past tense.

* Also, the part “I would be famous one day” is an assertive sentence. Thus, we will not use “asked” here.

The correct sentence will be: My teacher told me that I would be famous one day.

Hence, option B is the correct answer.

Suspension = the act of stopping something happening, operating, etc. for a period of time

Information = facts about a situation, person, event, etc.

Dereliction = (a) failure to do what you should do

Revolution = a very important change in the way that people do things

Benediction = a prayer asking God for help and protection for someone

* In the context of the given sentence, “suspension” doesn’t fit here.

* We can reveal a secret or “some information” only.

* Thus, the underlined part will be replaced with “information”.

Hence, option A is the correct answer.

* The part “for atleast 10 years” shows that the sentence is in the present perfect tense.

* This tense represents an action or situation that started in the past and continues in the present.

* With the plural subject “they”, we will use the plural auxiliary “have” followed by V3 (known).

The correct sentence will be: My brother and Raj are good friends. They have known each other for at least 10 years.

Hence, option C is the correct answer.
