americans were buying radios and televisions. they began going to the movie theater regularly. as a result however in addition ← joining words use one of the joining words to connect the ideas. your response may be one sentence or two.
Answer
Brief Explanations:
The two sentences describe additional leisure activities Americans were engaging in (buying radios/TVs and going to movie theaters). "In addition" is appropriate as it adds another related action. "As a result" implies a cause - effect (not present here), and "however" implies contrast (also not present). So using "in addition" connects the ideas well, e.g., "Americans were buying radios and televisions. In addition, they began going to the movie theater regularly."
Answer:
Americans were buying radios and televisions. In addition, they began going to the movie theater regularly. (Or other valid sentences using "in addition", "as a result" would be incorrect as there's no causal link, "however" is incorrect as there's no contrast. So the appropriate joining word is "in addition" and a sample sentence is as above.)
