Answer» Out of the given SENTENCES, the only correct sentence is 4. The sentence uses the conjunction 'lest', which means to avoid the risk of something unpleasant. e.g. She did not speak out loud, lest she disturb anyone. So, by using 'lest', the sentence means 'you must take care-so that you avoid the risk wherein-you fall.' This means that the sentences that USE a negative verb oughtn't, mustn't etc. are incorrect, as they change the meaning of the sentence. So, options 1 and 2 are incorrect. Option 3 uses the preposition 'in', which is ALSO incorrect, given the context. Option 5 uses the conjunction 'unless', which means 'except if', which also changes the meaning of the sentence and hence is incorrect. Therefore, the correct answer is option 4. |
