Answers :

1) Answer: B

The original sentence is incorrect.

Reason: There are two errors in the bold phrase.

1^st. Instead of ‘product’ noun form‘production’ should be used here.

2^nd. In the sentence, the writer refers to the subject ‘on the’ and not ‘of the’. Therefore, ‘on the’ should be replaced by ‘of the’ to make it a meaningful sentence.

Therefore, among the given choices option B replaces the bold part most appropriately.

The sentence after replacement becomes:

Concerns regarding Covid-19 vaccine wastage were raised as SII began production of the Covid-19vaccine before being granted emergency use authorisation for use in India on January 3

Therefore, option B is the correct answer choice to this question.

2) Answer: E

The original sentence is absolutely correct and needs no correction.

Therefore, option E or B is the correct answer choice to this question.

3) Answer: D

The original sentence is incorrect.

Reason: 

1^st. As we can observe that the sentence is made in past tense, usage of present form ‘manufacture’ is erroneous here. Instead of ‘manufacture’, ‘manufactured’ (because the subject is singular) should be used here.

2^nd. ‘of the’ means ‘expressing the relationship between a part and a whole.’ and the word doesn’t make any sense in the context of the sentence. Instead ‘by the’ which means ‘identifying the agent performing an action’ should be used here.

Therefore, among the given choices option D replaces the bold part most appropriately.

The sentence after replacement becomes:

Covishield, which has been developed by Oxford-AstraZeneca against Covid-19, is locallymanufactured and sold by the Serum Institute of India (SII).

Option D is hence the correct answer.

4) Answer: C

The original sentence is incorrect.

Reason:

1^st. The word ‘authorisation’ and not ‘authorise’ is used to denote official permission. Therefore, ‘authorise’ must be replaced by ‘authorisation’ here.

2^nd. As the preposition ‘at the’ is used in its plural form, it’s clear that the subject has to be plural too. Therefore, the preposition ‘at the’ must be replaced by ‘by the’ here.

Therefore, among the given choices option C replaces the bold part most appropriately.

The sentence after replacement becomes:

The process is, when any drug or a vaccine is given, emergency use authorization is given by the drugs controller general of India.

Option C is hence the correct answer.

5) Answer: C

The original sentence is erroneous.
Reason: The sentence implies a contradiction of thoughts and therefore usage of 'towards’ as a preposition is absurd here. Instead, that implies the same context `to’ should be used.

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

The sentence after replacement becomes:.

As the drug or the vaccine becomes older, there is addition to the data and further extensions are given on the basis of stability and sterility data.

Option C is hence the correct answer.
