A statement with one blank is given below. Choose the set of words from the given options which can be used to fill the given blank.
You should ____ swimming.
Explanation: 'take up' means to become interested or engaged in a pursuit. Hence, it is the right usage.
A statement with one blank is given below. Choose the set of words from the given options which can be used to fill the given blank.
Nowadays, she ____ her drawing board to school.
Explanation: 'carries' is correct because the sentence is in present tense and 'she' is a singular pronoun.
A statement with one blank is given below. Choose the set of words from the given options which can be used to fill the given blank.
She ____ be very silly at times.
Explanation: Both 'can' and 'could' are modal verbs that refer to 'a possibility', 'ability' or 'capacity'. 'Can' refers to a general truth or something that has a strong sense of possibility. 'Could' refers to something that has a weak possibility, or something that might happen, but is not necessarily a general truth. Hence, 'could' is the suitable answer here.

Which of the following is/are true as per paragraph 4? <br><br> I. Recycling the lead-acid battery is similar to recycling lithium ones. <br> II. Re-using batteries is a fundamental part of the mobility business. <br> III. Recycling lithium batteries is still at an early stage globally. <br>
Explanation: Refer to: I. ‘In India, the traditional lead-acid battery business successfully created a parallel industry of battery breaking units and recycling. Operating these was relatively easier; but handling lithium and its chemistries is a different ball game altogether.’ <br> I is incorrect. <br> II. ‘Planning for reuse of “end-of-life” batteries should, in fact, be a part of any electric mobility business case’<br> II is incorrect as the paragraph states that it should be an integral part and not that it is. <br> III. ‘Battery recycling, especially for lithium batteries, is still at an early stage globally.’ <br> III is correct. <br> Hence, option A is correct.
