Whаt dоes the wоrd ensure meаn in pаragraph 2? 2 Depending оn the time and the weather, the giant pandas have a choice to be outside or inside the panda house. The pandas typically have outdoor access until early afternoon. The panda house, an indoor viewing area, is open to visitors from 9 a.m. to 4 p.m. during winter hours and 9 a.m. to 6 p.m. during summer hours. Please check the hours page before your visit to ensure the Panda House is open. Early arrival is recommended to avoid large crowds and long lines. Long lines require earlier cut-off times to ensure those waiting can enter the panda house before it closes. Please note that all of the Zoo's animals have the option to enjoy some time away from the crowds. If the pandas are not on view, they may be spending time in an enclosure behind the scenes. Flash photography and video with handheld devices are permitted inside the panda house. For the safety of our visitors, the use of tripods is prohibited.
Whаt is the best synоnym fоr the phrаse pоtentiаl impact in paragraph 13? 13 The gift allows the Zoo's animal care and the Smithsonian Conservation Biology Institute's scientific team to proceed with the five-year science plan established with their Chinese colleagues from the China Wildlife Conservation Association. The science plan hasspecific goals: to examine the creation and impact of corridors to link fragmented habitats that will benefit giant pandas and other wildlife species, including promoting genetic diversity; examine how to restore habitats, especially those where pandas appear to be making a comeback; provide advice on giant panda reintroduction; examine the potential impact of transmissible diseases on giant pandas and other wildlife species, including providing advice on implementing new programs associated with a Wildlife Disease Control Center being built in Sichuan Province; and continue research on giant panda reproduction and management, because, although there has been major success in Chinese breeding centers, some pandas still experience reproductive challenges.
