Unfortunately, you forgot to attach the text for reference. Without the text, how can we read the information needed to answer your question. You also forgot to attach the options for this question.

However, trying to help you, we can comment on the following.

The author describes the different robots scientists are creating with a computer program "to show a variety of ways that robots could move."

Scientists from Cornell University in New York, are working hard in their laboratories trying to design new robots that look very different from what humans can imagine how a robot looks like.

These scientists have called these robots "softbox." Robots with soft tissue that can move more like a human, with flexible movements, instead of slopy, rigid movements like the ones we see on TV or in the movies.

Option C is the correct answer.

The weary employees dreaded the long, boring meetings.

There are two adjectives, which need a comma in between them.

(Clarification)

The skeleton of the sentence is:

(subject)(predicate)(direct object)
(employees)(dreaded)(meetings)

In this sentence, the words "long, boring" modify the direct object "meetings".

Since there are two adjectives, they need a comma to separate them.

Hope this helps!
