سوال ۳۶ کنکور ارشد مدیریت کسب‌وکار (MBA) ۱۴۰۲

Passage summary: Pandas remain popular but endangered, with wild populations confined to isolated Chinese mountain ranges and threatened by habitat destruction, illegal hunting and fragmentation. Transport routes divide populations and impede reproduction, despite the protection offered by reserves. Paragraph 3 contrasts pandas' almost entirely bamboo-based diet with their classification as carnivores. It then uses “Because of this” to introduce research on how climate-related bamboo loss could make their north-western Chinese habitat unsuitable.

What does the underlined ‘this’ in paragraph 3 refer to?
