Thanks, Kitty! XD

Your welcome Mary! :D

The sentence in question is a simple sentence.

To determine the answer, look for the subject and the predicate in the sentence. In this case, the subject is "The bicycle path" and the predicate is "winds through the city that is 40 miles long." Since there is only one independent clause and it expresses a complete thought, it is a simple sentence.

The other options can be eliminated as follows:
- A noun clause would function as a noun and usually starts with words like "that," "whether," or "if." However, the phrase "that is 40 miles long" is not functioning as a standalone noun.
- A misplaced modifier occurs when a phrase is incorrectly placed and causes confusion or modifies the wrong part of the sentence. However, there is no misplaced modifier in this sentence; the phrase "that is 40 miles long" correctly modifies the city.
- An adverbial clause would modify a verb, adjective, or adverb and typically starts with a subordinating conjunction like "when," "where," "although," etc. The phrase "that is 40 miles long" does provide additional information, but it doesn't modify the action of the verb "winds through." Instead, it modifies the noun "city."

In summary, the correct answer is a. Simple sentence.
