How should sentences 4 and 5 be combined for better flow?

Combining sentences for better flow often involves recognizing similarities and differences in the information presented. The focus of sentences 4 and 5 is on the tools used in knitting and crochet—specifically the number of utensils required for each craft.

The correct answer effectively emphasizes the contrasting tools: knitting requires two needles, while crochet only requires one hook. This clear differentiation maintains the focus on the specific aspect being discussed—tools—while also creating a logical flow that ties the two sentences together. By presenting the two techniques in this structured manner, the reader can easily follow the comparison being made.

In contrast, while the other options touch on knitting and crochet, they do not maintain the focus on the utensils. For example, discussing the complexity of each craft or their artistic purposes diverts from the primary point of comparison regarding the tools, leading to a loss of clarity and purpose in connecting the sentences.
