1. The largest instant noodle manufacturer in a country plans to raise the price of instant noodles by 10% to 20% in April. This will be the first time that the price of instant noodles in the country has risen sharply since FY2006, approaching an all-time high. The company said that the reason for raising the price of instant noodles is mainly to cope with the rise in the price of raw materials such as grain.
One that best supports the above assertion is:
a In the face of the rising trend of the price of raw materials such as grain in the international market, the government of country A has issued a policy to prohibit domestic grain processing enterprises from increasing the price of grain products, so as to prevent the people of country A from increasing the cost of living and increasing the burden
b The domestic supply of raw materials such as grain in Country B is sufficient, but due to the increase in labor prices, the production costs of grain processing enterprises have increased, resulting in an increase in the price of grain products such as instant noodles
The domestic supply of raw materials such as grain has been very abundant, and recently there has been a large-scale improvement in agricultural production technology and increased grain production, and the price of food products such as instant noodles in the country has been stable
Workers of dingguo grain processing enterprises held a general strike, resulting in the paralysis of the country's grain processing enterprises, and the shortage of grain products such as instant noodles in the country, and the country had to rely on imported grain products
Step 1: Look for cause and effect
Reason: In order to cope with the rise in the price of raw materials such as grain
The result: One of the country's largest instant noodle manufacturers plans to raise the price of instant noodles by 10% to 20% in April
Step 2: Analyze the options
a Option: Causes and consequences of the stem: In order to cope with the increase in the price of raw materials such as grain, a certain country decided to increase the price of instant noodles. Item a, taking Country A as an example, illustrates that the rise in the price of raw materials such as grain in the international market may lead to an increase in the price of grain products, which supports the causes and consequences in the stem. So choose a.
Option b: The content of the option indicates that the increase in the price of instant noodles may be caused by the increase in labor prices, which cannot support the stem, so b is wrong.
c Option: The content of the option only shows that the adequate supply of raw materials such as grain and the large-scale improvement of agricultural production technology are conducive to the stability of the price of grain products, and does not directly indicate that the price of grain products will rise when the price of raw materials such as grain rises. So c wrong.
d Option: The content of the option is about the specific reasons that cause the Country to import food products, which has nothing to do with the medium price of the stem. So d wrong.
Therefore, the topic is a.
220 million years ago, when dinosaurs ruled the earth, a small group of nocturnal ancient reptiles unknowingly found a survival strategy and eventually went the way to brain evolution. Scientists have concluded from fossil skulls of ancient reptiles that are very similar to primitive mammals that it was the development of the sense of smell that contributed to the evolution of the brains of ancient reptiles.
Which of the following, if true, best supports the above conclusions:
Many early mammals naturally evolved smaller bodies, but their brains failed to shrink in proportion
b The researchers analyzed the reptile cannitosaurus
Stone, closely related to the early mammal Morgan, but the Morgan beast had a brain that was one year older than that of canine-toothed dragons
times, where the area where the sense of smell is processed is significantly enlarged
c Early nocturnal mammals evolved larger brains
To promote their hearing, because vision at night
It doesn't make a big difference
D Studies have shown that the relationship with living mammals is closest
Megacranium, its brain capacity and nasal cavity take up space
It was larger than the early reptiles
Cause: Olfactory development
The result: brain evolution
The stem concludes that the development of the sense of smell leads to the evolution of the brain, and to support it, it is necessary to bridge between the two. B supplementary arguments deal with the larger olfactory region of animal brains, support stems, elected.
A, c options: none of them explained the effect of smell on the brain, irrelevant items, exclusion.
d option: the large space occupied by the nasal cavity does not indicate that the ability to deal with smell is strong, irrelevant items, so d is wrong.
Therefore, B is selected for this topic.
3. A residential community theft cases occur frequently, at the request of the residents of the community, the property installed a multi-functional anti-theft system for the community at the beginning of last year, and the incidence of theft cases in the community dropped significantly, which shows that the multi-functional anti-theft system can effectively reduce the incidence of theft cases.
Which of the following, if true, would best reinforce the above conclusions:
a In the past year, there has been a significant increase in the number of thefts in residential quarters where such a theft system is not installed
This anti-theft system was also installed in another residential area near b, but it did not work well
c Since the beginning of last year, the city has strengthened policing and the number of thefts has decreased significantly
d Property takes other anti-theft measures, which also play a certain role in preventing theft cases
Reason: Install a multi-functional anti-theft system
The result: a significant decrease in the incidence of theft
It is necessary to strengthen the stem of the problem, indicating that the multi-functional anti-theft system can indeed reduce the incidence of theft. Option a indicates that the incidence of theft in the community without the system is installed, and adds that the installation of the system can reduce the theft rate, support the stem, and is elected.
Option b: Installed but the effect is not good, indicating that the theft rate cannot be reduced, weakening the stem, so b is not selected.
c option: It is stated that the theft cases have been greatly reduced due to the strengthening of public security, which belongs to other reasons and weakens the stem, so c is not selected.
d option: the stem is to say multi-function anti-theft system, the option is to say other measures, the topic is inconsistent, belongs to the irrelevant item, so d is not selected. Therefore, the topic is a.
