» Explain it
B
The original sentence is incorrect.

Reason: When the sentence contains two actions, both of them should not be in the future tense. The action which takes place first should be in the simple present tense. In the given sentence, the first action is getting the green signal and the second action is starting the race. Therefore, ‘will’ should be omitted so as to make the sentence correct.

Among the given choices option B replaces the bold part most appropriately.

The sentence after replacement becomes:

We will start the game when we get a green signal from our technical team.

Option B is hence the correct answer.

B
The original sentence is erroneous.

Reason: Usage of the phrasal verb 'carry on' which means ‘continue an activity or task' is inappropriate in this sentence.

'Carry off' which means ‘to cause the death of’ would be suitable in this context.

E.g.: The plague carried off thousands.

Hence ‘carries off’ should be used in place of ‘carries on’ for making the sentence grammatically and contextually correct.

Among the given choices, only option B replaces the given bold part most appropriately.

The sentence after replacement becomes:

Malnutrition carries off thousands of children across the globe every year.

Option B is hence the correct answer.

India has already breaking the backbone of GST implementation but there is still a long way to go.
» Explain it
C
The original sentence is erroneous.

Reason: The correct idiomatic expression in this sentence is ‘broken the back of ' and not ' breaking the backbone of’.

Break the back of (Idiom):

Meaning: Accomplish the main or hardest part of a task.

E.g.: We've broken the back of the problem.

 Hence, ‘broken the back of’ should be used in place of ‘breaking the backbone of’ to make the sentence grammatically correct.

Among the given choices, only option C replaces the given bold part most appropriately.

The sentence after replacement becomes:

India has already broken the back of GST implementation but there is still a long way to go.

Option C is hence the correct answer.

Option E is hence the correct answer.
 
» Explain it
B
The original sentence is erroneous.

Reason: The term ‘each’ follows singular form. Each boy and each girl is individually and not as a group. So the singular form of the be verb should be used. Hence ‘is’ should be used in place of ‘are’ in order to make the sentence grammatically correct.

Among the given choices, only option B replaces the given bold part most appropriately.

The sentence after replacement becomes:

Each boy and each girl is requested to be in school uniform tomorrow. Option B is hence the correct answer.
