Question

8 what are signal words?
words that introduce new topics
words that define other words
words that indicate connections between ideas
words used in a thesis statement

Explanation:

Signal words (also called transition words) are used to show relationships between ideas, like cause - effect, addition, contrast, etc. The first option is incorrect as introducing new topics isn't their main role. The second is wrong as they don't define words. The fourth is incorrect as they aren't limited to thesis statements. The third option matches the definition of signal words.

Answer:

C. words that indicate connections between ideas (assuming the options are labeled A, B, C, D with the third option being C; if the original labels are different, adjust accordingly. Since the options are presented in order, the correct one is the third option: "words that indicate connections between ideas")
