Question 5:
Choose the most appropriate option to change the narration (direct/indirect) of the given sentence.
Mary said, "I have to be there by 10 am tomorrow."
Mary says to me that she has to be there by 10 am
Mary tells me she has to be there by 10 am tomorrow
Mary told me that she had to be there by 10 am the next day.
Mary is telling me that she has to be there by 10 am tomorrow
The correct answer is option 3.
The speaker is informing something i.e told will be used. Tomorrow will be changed to the next day in indirect speech. The first person pronoun will be changed to the third person i.e. she.
Also, the past participle form of the verb will be used. So option 3 is correct.

Thousands crowded grocery stores, vegetable shops and petrol pumps to stock up, many ignoring safety norms.
Which of these should be filled at (1) as per the context of the passage?
increasing
intensifying
elongating
enhance
The correct answer is option 2, i.e. intensifying.
The passage is about Tamil Nadu's government's order in reference to lockdown. It deals with upcoming threats which are likely to surface if restrictions are lifted.
•Let us look at the usage of the words given in the options:
• Increasing is used in context of quantities, so as per the context it is not suitable.
• Enhance is a verb. Here, use of this is contextually and grammatically incorrect.
• Elongating is used for physical quantities, so here it is ad incorrect since lockdown is not a physical quantity.
• Intensifying is used to indicate an enhancement in thequality of something. Here, it is suitable because the passage talks about increment in the quality of the already imposed lockdown.
The other three options do not fit contextually and grammatically.
Hence, intensifying is correct
