1.Many animal bones have been found in caves with the bones of Pleistocene primates, some believe to be the ancestors of humans. Judging by the frequency with which various bones appear, many animals die elsewhere, and only certain parts of their bodies are brought back to their burrows. Therefore, to be able to bring back so much prey, the primates of the Renewal Epoch must be good at hunting.
Which of the following, if correct, most seriously weakens the above conclusion?
a.The imprints on all bones, including the remains of primates from the Pleistocene, are the tooth marks of a large carnivore of that era.
b.The bones in the cave do not include the bones of an elephant-like animal from the same period as the Pleistocene primates.
c.There is no evidence of the use of fire in the caves where animal bones were found.
d.Pleistocene primates sometimes move from cave to cave in search of shelter, and they spend their lives in more than one cave.
2.A city held a folk culture and art exhibition, Xiao Li, Xiao Zhang, Da Wang and Lao Xu will be the inheritors of paper-cutting, Suzhou embroidery, Baiju and Kunqu opera for on-site performances, each of which will be performed one by one, and the performances will be carried out one by one. The organizer also has the following arrangements:
1) Lao Xu's performance should be ranked behind paper-cutting and Suzhou embroidery;
2) Xiao Li can only ** during the performance of Baiju and Kunqu Opera;
3) The king's performance should be in front of the paper-cutting;
4) Xiao Zhang's performance should be in front of Kunqu Opera and Lao Xu's performance.
Based on the above arrangement, which of the following can be derived?
a.Xiao Li performed paper-cutting, ranking 1st.
b.Dawang performed Suzhou embroidery, ranking 2nd.
c.Xiao Zhang performed Kunqu Opera and ranked third.
d.Lao Xu played the white game and ranked 4th.
3.Studies have found that what moms eat regularly during pregnancy will give their children what they like to eat in the future. This is because when the fetus develops in the mother's womb, it thinks that all the food ingredients ingested by the mother are safe and remembers the taste of the food in the nervous system as a basis for its own future search for food.
Which of the following conclusions cannot be drawn from the above studies?
a.If a pregnant woman is malnourished during pregnancy, the child will be picky eaters after birth and will not like to eat nutritious food.
b.Pregnant women who eat meat regularly should eat a balanced diet to prevent their children from being too meat-preferred after birth.
c.Pregnant women need to be careful not to drink alcohol as much as possible, and if the fetus feels the taste of alcohol, the likelihood of alcohol abuse increases later.
d.Pregnant women should maintain a healthy diet and eat more healthy foods to help their children have healthy eating habits in the future.
4.Studies have shown that exercise, especially a lot of exercise, increases the level of serum in the body. To some extent, a person's mood is determined by the level of serum in the body. Antidepressants can work by increasing the level of serum bases in the body.
The following assertions must be true:
Increase serum levels in the body, either by exercising a lot or taking antidepressants.
A person's mood may be determined by the amount of exercise exercised and may also be affected by antidepressant medications.
Exercising a lot can affect a person's mood or affect the effectiveness of antidepressant medications.

5.In the face of the energy crisis, some countries have begun to look for alternative energy sources, and the use of corn to process ethanol gasoline for vehicles is no longer new. Therefore, many people believe that the use of corn to produce energy can not only digest the aged grain in stock, but also develop alternative energy for oil, which will be one of the trends of energy development in the future and a policy for the benefit of the country and the people.
Which of the following, if true, does not weaken this conclusion?
a.At present, it seems that the production of ethanol gasoline for vehicles will consume a lot of water.
b.Ethanol gasoline can cause severe corrosion to critical components such as a vehicle's engine.
c.The use of corn as an energy source for production can appropriately increase the quality of corn, thereby increasing farmers' income and farmers' enthusiasm for growing grain.
d.It takes 3 to produce 1 ton of ethanol3 tons of corn, so that nearly 10,000 tons of corn will be consumed every year, which will endanger the country's grain reserves.
On January 31, the public *** daily practice: logical judgment (analysis).
1.【Answer】a. Analysis: The question stem is from "A lot of animal bones were found in the cave of the Pleistocene primate bones" to "The Pleistocene primates must be good at hunting". a states that these animals, including Pleistocene primates, are prey to large carnivores, which directly weakens the conclusion of the stem; B, c, and d are not related to whether Pleistocene primates are good at hunting. So the answer is A.
2.【Answer】d. Analysis: From (1) it can be known that Lao Xu does not perform paper-cutting and Suzhou embroidery, from (2) it can be known that Xiao Li does not perform Baiju and Kunqu Opera, from (3) it can be known that Dawang does not perform paper-cutting, and from (4) it can be known that Xiao Zhang and Lao Xu do not perform Kunqu Opera, which can be listed as follows**:
It can be seen from ** that Lao Xu performed the white game, Dawang performed Kunqu Opera, and Xiao Li and Xiao Zhang performed paper-cutting or Suzhou embroidery respectively. In addition, according to the conditions of (1), (3) and (4) of the question stem, it can be seen that the corresponding performance order from small to large is:
From the table, it can be seen that Xiao Zhang does not perform paper-cutting, then Xiao Zhang performs Suzhou embroidery, Xiao Li performs paper-cutting, Xiao Zhang is in the 1st place, Dawang is in the 2nd place, Xiao Li is in the 3rd place, and Lao Xu is in the 4th place. So the answer is D.
3.【Answer】a. Analysis: Stem studies have found that what mothers often eat when they are pregnant will like what their children will like to eat in the future. B, C, and D can all be introduced from the question stem; Malnutrition during pregnancy is not necessarily the fact that the food is not nutritious, and whether the food is nutritious or not cannot be judged from the taste, and item a cannot be deduced from the stem. So the answer is A.
4.【Answer】d. Analysis: The question stem only states that exercise and antidepressant drugs can increase serum levels, which in turn affect mood, but it does not say that serum levels are only affected by these two ways, so it is wrong and correct. If one of the propositions is true, the whole proposition is true, so it is correct. So the answer is D.
5.【Answer】c. Analysis: The stem point of view is that the use of ethanol gasoline for corn processing vehicles can replace petroleum energy, which is a development trend of future energy. Item A consumes water resources, item B causes serious corrosion to key parts of automobiles, and item D endangers grain reserves, all of which indicate the disadvantages of corn as an energy source for production, which weakens the topic of the topic. c points to the advantages of using maize as an energy source for production, which in turn supports the stem view. So the answer is c.
