The researchers gave the same food to a group of experimental mice, some of which had irreversible damage to the hypothalamus, while others did not. After a while, the researchers found that mice with damage to the hypothalamus showed signs of obesity. The researchers believe that damage to specific parts of the hypothalamus is the cause of obesity in mice.

In one experiment, the researchers investigated the level of physical activity of the subjects and analyzed the average amount of time they spent sitting every day. The results showed that sitting for too long (more than 5 hours) was closely related to the shrinking of the medial temporal lobe of the brain, and even if the body reached a high level of activity at other times, it could not change the trend of shrinking the temporal lobe. Therefore, sitting for a long time can have an effect on people's memory.

Question: Which of the following premises needs to be added to reach the above conclusion?

Choices:
- A.Some people with poor memory do not exercise often and prefer to stay at home
- B.Most patients with Parkinson's disease have persistent memory decline and shrinking temporal lobe

Question: Which of the followings, if true, can best support the above argument?

Choices:
- A.Mice living in areas with long sunshine are less likely to develop early Alzheimer's disease than laboratory mice exposed to light stimulation
- B.Some mice that have received light stimulation suffer from early Alzheimer's disease

The mainstream view is that climate change is the main driving force of human biped walking. Millions of years ago, the area of forests in Africa began to shrink and the area of grasslands increased greatly. In an environment with few trees, the significance of biped walking is clear: standing up allows human ancestors to look beyond the lush grass to see predators and prey. As a result, the massive increase in the area of grasslands has made the ancestors who are the most good at standing more likely to survive and pass on their genes.

Question: Which of the followings, if true, most weakens the above argument?

Choices:
- A.In the process of human ancestors' walking from four legs to two feet, many body structures have changed
- B.In the area where early bipedal walking human fossils were found, a large number of contemporary forest animal and plant fossils were also found
- C.Newborns show signs that some human ancestors used to live in trees
- D.The knee joints of early humans are strikingly similar to those of modern humans


Nowadays, people often complain that it is difficult for them to get enough sleep, and the quality of sleep is often poor.

Question: Which of the followings, if true, can best support the above conclusion?

Choices:
- A.When individuals are exposed to light, falling asleep becomes more difficult than before, and sleep is fragmented
- B.Modern people's circadian rhythms are often disrupted by work and jet lag, and electronic devices and artificial light sources are not the only reasons for sleep interruptions
- C.At present, some people's sleep problems are probably not due to the short total sleep time, but because of some health problems caused by the use of computers and other devices
- D.In some rural areas where there is no electricity, the average sleep time of people is much longer than that of their peers living in cities


Although footprint fossils can not preserve the complete morphology of organisms like solid fossils, we can analyze the general morphological and behavioral characteristics of organisms from footprint fossils. In other words, when there is a lack of direct evidence, we can only use indirect evidence-footprint fossils to speculate about the environment, which animals left footprints, whether they have complex animal behavior and so on. Therefore, during the transition period from Precambrian to Cambrian, footprint fossils are particularly important.

Question: Which of the following premises is necessary for the establishment of the above conclusion?

Experts believe that once myopia occurs, it is irreversible. In particular, children with myopia at a low age are more likely to become highly myopic, resulting in visual impairment. Full exposure to sunlight can effectively protect eyesight. Outdoor activities of 2 hours a day and more than 10 hours a week can reduce the incidence of myopia in teenagers by more than 10%. This is mainly because the light intensity of the sun is hundreds of times higher than that of indoor light, the stronger the light is, the more dopamine is released, and dopamine can inhibit the occurrence and development of myopia.
