Question

Read the sentences.

Many vegetables are the roots of plants. Carrots are roots. Beets are as well. However, carrots are usually long and slender, while beets are red and round.

Which word or words signal that two things are being compared?

while
are usually
as well
however

Answer 1

In the given sentences, 'while' and 'however' are used as signal words to indicate that a comparison is being made between the characteristics of carrots and beets.

Step-by-step explanation:

The words that signal two things are being compared in the sentences are 'while' and 'however'. These words are used to introduce a contrast between the characteristics of carrots and beets. When 'while' is used, it is indicating that there is a simultaneous difference in traits, showing how carrots being long and slender is in contrast to beets being red and round. 'However' serves as a transition to introduce the differing traits following a statement about similarities.

Answer 2

While and however

Step-by-step explanation:

"are usually" refers to the common shape of the carrot (which is not what we need).

"as well" tells you that beets and carrots are similar, but shows no sign of comparison.

"however" and "while" are left.
