Question

question 17 of 20 : select the best answer for the question. 17. a lone male wolf, who doesnt have a pack, travels the forest. when he reaches a new hill that he hasnt been on before, he spends a large amount of time sniffing the trees and rock outcrops. finally, he turns and heads back from where he came, recognizing this is the territory of another wolf. whats most likely responsible for communicating this information to the wolf?
a. language
b. pheromones
c. markings on the trees
d. the tracks of other wolves on the hill
mark for review (will be highlighted on the review page)

Explanation:

• Option A: Wolves don't use language as humans do, so A is incorrect.
• Option B: Pheromones are chemical signals animals use to communicate, like marking territory. The wolf sniffing (detecting pheromones) makes this likely.
• Option C: The question implies chemical communication (sniffing), not visual markings, so C is less likely.
• Option D: The wolf is sniffing, not focusing on tracks, so D is incorrect.

Answer:

B. Pheromones
