Relative clauses are nonrestrictive if their meaning

is not indispensable to the superordinate clause.

Match each text sample with its correct description.

Gapping is a subcategory of complex postponement.

The phrase 'a report on short poems and novels' is

ambiguous because:

The subordinator 'that' does not have any syntactic

function in the structure of appositive clauses.

The Adverbial of agent is specific to a passivized

sentence only.

Disjuncts are not Adverbials because they do not show

time, place, condition, purpose etc.

Both wh- relative adjectives and wh- relative pronouns

can have syntactic functions in a relative clause.

No relative clause can be a Subject because it is

introduced by a subordinator.
