Answer:
1, 2 and 5 are clauses while 3 and 4 are phrases.
Explanation:
Clauses are those groups of words that have both a subject and predicate in the it whereas phrases have just a subject or a predicate in it. phrases do not have both subject and predicate.
1. My uncle told me a funny story about a mistake <u>that he made at a hotel in Paris</u>. Clause
2. Uncle Nestor, <u>whose French is not very good</u>, went to the front desk to ask for an extra blanket. Clause
3. The clerk <u>at the desk</u> looked puzzled. Phrase
4. It turns out that uncle Nestor had confused the word for blanket with the word <u>meaning "flag"</u>. Phrase
5. The clerk thought my uncle wanted to wrap himself in a flag, <u>which would not be very warm</u>. Clause
Therefore, sentences 1, 2 and 5 have both the subject and predicate in them, while the others are phrases.
