The boat will carry you____the river

In order to fill in the blank and complete the sentence, we need to understand the relationship between the boat and the river. The boat is typically used to navigate or travel across a body of water, such as a river. Therefore, the missing word should indicate the direction in which the boat will travel in relation to the river.

To determine the missing word, we can consider prepositions that express movement or direction. Some common prepositions that can be used when talking about crossing a river are "across," "over," or "along." Each preposition conveys a slightly different meaning:

- "Across" suggests crossing from one side of the river to the opposite side.
- "Over" implies moving above the surface of the river.
- "Along" indicates traveling in the same direction as the river, often alongside its banks.

Without more context, it is difficult to determine the specific preposition that should fill the blank. However, you can choose the most appropriate preposition based on the intended meaning of the sentence.
