Choosing the Correct Preposition for Rivalry

The question asks us to select the appropriate preposition to complete the sentence: "The rivalry _______ the two groups increased after the elections."

We need to consider the options provided and how each preposition is typically used.

Understanding Prepositions for Relationships

Prepositions often show the relationship between different parts of a sentence, including spatial relationships, time, or abstract relationships like rivalry or agreement.

Let's look at the options:

• between: This preposition is typically used when referring to two distinct people, places, or things. It indicates a relationship, division, or connection involving these two entities.
• amongst: This preposition is typically used when referring to three or more people, places, or things, or when the entities are not specifically named or considered individually. It indicates being surrounded by or in the midst of something.
• in: This preposition often indicates location (within something), time (during a period), or a state/condition.
• at: This preposition often indicates a specific point (location or time), direction, or rate.

Analyzing the Sentence

The sentence specifically mentions "the two groups". This clearly indicates that the rivalry involves exactly two entities. When we talk about a relationship or interaction involving two distinct items or groups, the preposition between is the standard choice.

For example:

• The agreement between the two companies was signed today.
• The ball is bouncing between the two players.

If the sentence had referred to more than two groups or a general sense of rivalry within a single large, undefined group, "amongst" might be considered. However, the explicit mention of "two groups" makes "between" the correct fit.

The prepositions "in" and "at" do not fit the context of describing a rivalry that exists *connecting* or *relating* the two groups. They are used for different types of relationships.

Conclusion

Since the rivalry is specifically stated to be involving "the two groups", the preposition that correctly expresses this relationship is between.

The completed sentence is: "The rivalry between the two groups increased after the elections."
