Correct Answer: Molly and her family were rescued by a lifeguard.

Solution : The first option is correct.

Passive voice is the voice in which the object experiences an action rather than the person who performs the action. Hence, the object in the active voice becomes the subject in the passive voice.

The structure of the passive voice in the case of the simple past tense is: "Plural object + were + past participle form of the main verb + 'by' followed by the agent of the action."

Therefore, the sentence in passive voice is: "Molly and her family were rescued by a lifeguard."

Correct Answer: lately

Solution : The error lies in the third option.

The term lately is an adverb used to describe actions that have happened recently. However, in this sentence, the intended meaning is to convey that Riya arrived at the train station after the expected or planned time. The correct term to use in this context is late, which is an adjective indicating a delay in arrival.

Therefore, the correct sentence should be: "Riya arrived at the train station late."

Correct Answer: NQDSZUNS

Solution : Given:
PLASTIC: QMZTUHD :: OPERATOR : ?

Add 1 in the positional value of consonant and subtract 1 from the positional value of vowels of PLASTIC, to obtain the code –
P + 1= Q, L + 1 = M, A – 1 = Z, S + 1 = T, T + 1 = U, I – 1 = H, C + 1 = D
Thus, PLASTIC is coded as QMZTUHD.
Similarly, follow the  same pattern for OPERATOR : ? –
O – 1 = N, P + 1 = Q, E – 1 = D, R + 1 = S, A – 1 = Z, T + 1 = U, O – 1 = N, R + 1 = S

Thus, OPERATOR is coded as NQDSZUNS. Hence, the third option is correct.

Her hands trembled as she took it. She fastened it around her throat, outside her high-necked waist, and was lost in ecstasy at her reflection in the mirror. Then she asked her friend, hesitating, filled with anxious doubt: 'Will you lend me this?'

Correct Answer: ADCB

Solution : The correct choice is the second option: ADCB.

Explanation: The sequence describes the actions in a coherent order. Initially, the person dips his fingers in milk and feeds the fawn (A). The fawn sucks greedily (D), but when the person withdraws his fingers, the fawn bleats frantically (C). To soothe the fawn, the person dips his fingers again and allows the fawn to suck them (B).

Therefore, the coherent paragraph would be: He dipped his fingers in the milk and thrust them into the fawn's soft, wet mouth. It sucked greedily. When he withdrew them, the fawn bleated frantically. So he dipped his fingers again and let the fawn suck them.

Correct Answer: she will already return home

Solution : The correct choice is the third option.

The correct construction should be: "She will already have returned home." This is because when expressing an action that will be completed before another future event, the future perfect tense is used.

In this context, she will already have returned home means that her return home will be completed before her parents get back.
