Final answer:
Sentence A is the claim, suggesting that traveling alone is negative. Sentence B provides a counterargument, highlighting the benefits and safety measures for solo travel. Sentence C acts as a rebuttal, asserting the importance of solo travel for personal growth.
Step-by-step explanation:
When considering the sentences provided, one can identify the claim, counterargument, and rebuttal among them. Sentence A - 'Traveling alone is dangerous and irresponsible' serves as the claim, positing a clear position on the topic of traveling alone. Sentence B - 'Traveling alone does not have to be dangerous because it teaches a person to be more aware of his or her surroundings and the traveler can visit crowded places' operates as the counterargument, offering a differing view that challenges the initial claim. Finally, sentence C - 'Traveling alone is essential to becoming a responsible adult' presents a rebuttal to the counterargument by pushing the argument further and stating that not only is traveling alone not dangerous, but it is a critical experience for personal development.
