Question

in science class today, ariel gave a speech against using fossil fuels to generate power. after she gave her speech, steven commented on it as she had presented and gave evidence to support his point.
the prefix contra- means \against,\ and the root dict means \speak.\ select the meaning of \contradicted\ as it is used in the paragraph.
○ showed support for
○ denied the truth of
○ asked a question about
○ gave practical examples of

Explanation:

To determine the meaning of "contradicted" in the paragraph, we analyze the word parts: "contra-" means "against" and "dict" means "speak". So "contradicted" here should mean opposing or denying the truth of what Ariel presented (since Steven contradicted her after she gave her speech and evidence). Let's check the options:

• "showed support for" is the opposite of what "contra-" implies.
• "asked a question about" doesn't relate to "against" or "speak" in the word's structure.
• "gave practical examples of" also doesn't fit the meaning of "against speaking" (i.e., opposing).
• "denied the truth of" fits as "contra-" (against) + "dict" (speak) would imply speaking against, or denying, the truth of what was said.

Answer:

denied the truth of
