Prepositions

To correctly match the sentences with the appropriate prepositions, we need to understand the context and typical usage of prepositions in English. Let's analyze each sentence:

• (A) "The edited version of her article is indistinguishable __________ her first version." The correct preposition here is 'from' because we typically say something is indistinguishable "from" something else. This matches with (IV).
• (B) "I just don’t feel any affinity __________ his prose style. It’s too caustic." The preposition 'with' fits here, as one usually has or doesn't have affinity "with" a particular style. This matches with (I).
• (C) "Her ideas are not all that dissimilar ___________ mine." The word 'to' is used here, as "dissimilar to" is the standard form. This matches with (II).
• (D) "It would be wrong to mistake his diffidence ___________ his arrogance or coldness." The correct preposition is 'for', as in "mistake something for something else." This matches with (III).

Thus, the correct option is: (A) - (III), (B) - (IV), (C) - (I), (D) - (II)

Step 1: Recognize correct prepositional usage.
The correct preposition that follows "interested" is in, not "on", "at", or "about".
Step 2: Correct the sentence.
The corrected sentence should be:
"She is interested in learning new languages."

The manager asked the team to complete the project _______ the end of the week.

In this context, it is essential to choose the correct preposition to convey the right meaning. Below is a brief explanation of each option:

1. Until: Indicates a continuous action that goes on up to a certain point. It is not suitable here as it suggests the action is happening continuously until the deadline, which is not the intended meaning.
2. By: Signifies a deadline for an action to be completed. This is the appropriate choice as it implies the action should be finished any time before or on the given deadline.
3. Since: References a starting point in time and would not make sense in this context, as it doesn’t relate to a deadline.
4. For: Indicates a period of time over which something happens, not a deadline, making it unsuitable here.

Considering the explanation above, the correct completion of the sentence is: by

Thus, the correct sentence is: The manager asked the team to complete the project by the end of the week.
