Fill in the blank with a suitable preposition:
The excerpt for the examination was taken ________ Oscar Wilde.
The preposition ‘from’ is used to refer to where something is derived or originated from. In the given sentence, the excerpt is taken from Oscar Wilde’s work. Therefore option D is correct. On the other hand, ‘to’ is used to show who gets something or to indicate the destination of something, which is the opposite of what the sentence attempts to convey. The excerpt cannot be given 'to' Oscar Wilde, it is given 'to' the students. Therefore option B is incorrect. ‘For’ is a preposition of reason that denotes who is meant to have or use something. The excerpt is not intended for Oscar Wilde, rather is taken from him. Hence option A is incorrect. ‘By’ is used to refer to the agent or the person who performs the action, which is once again irrelevant here because Wilde is not the agent who selects the excerpt. Thus option C is incorrect.
