Professor Zhang: Since the 1980s, the number of spotted owls has fallen sharply and is now in danger of extinction. Timber harvesting companies should be held responsible for this, and the old forest areas they have harvested heavily are owl habitats. The decline in the number of owls cannot be attributed to the timber harvesting company. In the past 30 years, a more fertile striped owl has entered the aged forest area and competed with the striped owl for survival resources. Which of the following most accurately summarizes Professor Li's rebuttal to Professor Zhang's point of view? ['Deny the premise of Professor Zhang, this premise is: the timber harvesting company has been logging in the old forest area.', "Questioning Professor Zhang's hypothesis that the owl can only survive in the aged forest area.", 'Propose another explanation for the decline in the number of striped owls.', 'pointed out that Professor Zhang exaggerated the negative impact of logging in old forest areas.']
