You will be given a definition of a task first, then some input of the task.
Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Question: Does androgen receptor modulation affect longitudinal growth of cultured fetal rat metatarsal bones?
Answer: Modulation of AR activity in the fetal rat growth plate does not affect linear bone growth. Extrapolating from these in vitro data, it could be speculated that oxandrolone stimulates longitudinal bone growth in treated children by acting indirectly rather than directly through AR activation in growth plate chondrocytes.
Output:
no
