Answer:
Because is the correct answer.
Step-by-step explanation:
The question refers to this:
"As Rainsford struggles in the water, the boat travels onward without him. Quickly, he retains his wits. Instead of panicking, he decides to head toward the sound of the gunshots. He does so _________ he realizes where there are gunshots, there are people. Hopefully, these people will be willing and able to help him."
Transition words are words that show the reader the relationship between different parts of the speech and make easier for the reader to understand how the ideas are connected. In the passage, the correct answer is because since the speaker wants to introduce a reason for the character to take the decision of not panicking.
