Determine if verb is a linking verb:

1. The American Falls lies within the US.
Ans. "lies" is a linking verb

2. The Horseshoe Falls lies within Canada
Ans, "lies" is a linking verb

Neither is a linking verb. They are followed by prepositional phrases and don't link with anything. Linking verbs need to be followed by a predicate noun, pronoun or adjective.

To determine if a verb is a linking verb, you need to consider what function it serves in the sentence. Linking verbs, also known as copula verbs, connect the subject of the sentence to a noun, pronoun, or adjective that identifies or describes the subject. They do not show action. Here's how you can identify linking verbs:

1. Look for the verb in the sentence. In the first sentence, the verb is "lies," and in the second sentence, the verb is also "lies."

2. Ask yourself if the verb is connecting the subject to a noun, pronoun, or adjective. In the first sentence, "lies" connects the subject "The American Falls" to the phrase "within the US." It does not demonstrate action but rather describes the position or state of the subject. Therefore, "lies" is a linking verb.

3. Similarly, in the second sentence, "lies" connects the subject "The Horseshoe Falls" to the phrase "within Canada." It also describes the position or state of the subject, which means "lies" in the second sentence is also a linking verb.

To summarize, both sentences use the verb "lies" as a linking verb because they connect their respective subjects to phrases that identify or describe their position or state.
