A clause may be a main clause, a subordinate clause, a noun clause, an adjective clause and adverb clause (All of the above).

Explanation:

A clause is a group of related words that have at least a subject and a verb. There are two types of clauses: independent or main (when the clause has a full meaning on its own) and dependent (when the clause does not express a complete thought and needs to be placed with another clause to make sense).

Furthermore, dependent clauses can also be classified as adjective clauses (when they describe nouns), adverb clauses (when they modify adjectives, verbs or other adverbs) and noun clauses (when they act as nouns).

an intensive pronoun is a pronoun that ends in self or selves, such as himself, herself, themselves, yourself, ourselves. since band members is a third person plural, the correct intensive pronoun would be themselves. if the band was talked about as a collective noun, itself would be the appropriate intensive pronoun. intensive pronouns are used to add emphasis to the noun it's modifying which is why it directly follows it.
