In that case, I recommend recourse to your text materials to find out what an adjective phrase is (and all the other concepts you don't know). Alternatively, you can use your web browser to look up what each of these words and phrases mean. For example:

The first sentence has an adjective clause, while the second and third sentences have compound sentence structures.

In the first sentence, "that she is holding" is an adjective clause because it describes the noun "basket." An adjective clause functions as an adjective and provides additional information about a noun or pronoun.

In the second sentence, "If you fail to plan" is an adverb clause because it starts with the subordinating conjunction "if" and modifies the verb "plan." An adverb clause functions as an adverb and provides information about the verb, adjective, or adverb in the main clause.

In the third sentence, "and I was late to the movies" is a compound sentence structure because it consists of two independent clauses connected by the coordinating conjunction "and." A compound sentence comprises two or more independent clauses that are joined together.

In the fourth sentence, "John was late to dinner" and "I was late to the movies" are two independent clauses connected by the coordinating conjunction "and," making it a compound sentence structure.

Finally, in the fifth sentence, "The price of admission is a can of food or a child's toy" is a simple sentence. A simple sentence consists of a single independent clause, which is the case here.

To identify the types of clauses and sentence structures, you can break down the sentence into its constituent parts and analyze the function of each word or phrase. Clauses are groups of words containing a subject and a verb, while sentence structures refer to how the clauses are organized in a sentence.

I'll be glad to check your answers.

I have no idea what any of these are!
