Answer: Answer: B. The author thinks the hike was too easy.
Explanation: The author sees twisting his ankle and being chased by a bear as no big deal when the ordinary person would see that as scary. These two details rule out A. The author thinks the hike was exciting, and D. The author thinks the hike was harrowing. This leave you with B. The author thinks the hike was too easy and C. The author thinks the hike was boring. I am inclined to believe that the answer is B. The author thinks the hike was too easy, since the author states in the very beginning that the hike was "totally" easy and he also states that being chased by a bear was "mildly" amusing.
