"everyday verbals" what role do both present and past participles serve in a sentence?

The correct answer is the role of adjective. Both non-finite verbs can perform the role of adjective in a sentence. The following examples show this role:

Present participle as adjective, which can be recognized from its "-ing" ending:

Look at the reading boy.

Past participle as adjective, which are formed by adding "-ed" to the verb:

Look at the washed car.

the mood is annoyed. they wish sandy was there do to the job right and since they dont like they way it came out now they are annoyed.

the sentence that best describes the tone of the passage from the radio broadcast compared to the passage from the book is b. the radio broadcast has a more surprised tone.

consider the text evidence: in the passage from the book, the description is more matter-of-fact. it is simply describing the things resembling little grey snakes, but there is no urgency in the description. on the other hand, in the passage from the radio broadcast, there is definetely urgency (you can tell from the expression used, "good heavens", which clearly indicates surprise.)
