c) Travel time during this period was dangerous; nevertheless, people needed to travel in groups for safety reasons.
d)The sentence is correct the way it is

Answer 1

Option 'a' is correct as it uses a semicolon and the conjunctive adverb 'therefore' to clearly indicate a cause-and-effect relationship between the danger of travel and the need for traveling in groups for safety.

Step-by-step explanation:

The student's question involves rewriting a sentence to correctly convey a cause and effect relationship. Among the options provided, option 'a' is the most accurate as it clearly links the cause, which is travel during the period being dangerous, to the effect, which is the need for people to travel in groups for safety reasons. This is similar to the example provided wherein because vehicles sped, which is the cause, a traffic signal was installed, the effect. Furthermore, using a semicolon followed by a conjunctive adverb 'therefore' correctly joins the two independent clauses while indicating a cause-and-effect relationship.
