Question:
Economist? The personal income tax in the United States is a progressive tax, and the tax law is extremely complicated.People who want to pay taxes honestly often make mistakes in reporting because of misunderstandings; and those who deliberately avoid taxes always find loopholes in tax laws.Generally speaking, the size of tax avoidance space is directly proportional to the complexity of the tax system, and the level of tax avoidance capacity is directly proportional to the taxpayer's income level.Most of the tax avoidance space created by complex taxes will be used by the rich, making progressive taxation less than the degree of progress required by the tax law, and its function of regulating distribution is also greatly weakened.
Question: If the following statement is true, which one provides the strongest support for economists' above argument?
 A. When filing taxes, 60% of the people in the United States need to hire professionals to report on their behalf, and 22% need to use tax reporting software to help them calculate.
 B. The Americans proposed the idea of "abolishing the progressive tax rate and implementing a single tax rate" in 1981.
 C. From 1988 to 2006, the income of the richest one in the United States increased from 15% to 22% of the national income, but their average tax rate fell from 24% to 22.8%.
 D. On September 17, 2011, the Wall Street movement broke out in the United States.Demonstrators claimed to represent 99 people in the United States to protest the greed and corruption of the financial industry and social injustice.

Question: The following statements all have similar "survivor bias" except

Question:
Research has found that insects “breathe” through the stomata system on their bodies.The stomata are connected to the trachea, and more and more layers of smaller and smaller air are attached from top to bottom, thereby bringing oxygen to the whole body.At the current level of oxygen in the atmosphere, the total length of the stomata system has reached the limit; if the total length exceeds this limit, the oxygen supply capacity will be insufficient.Therefore, it can be judged that the amount of oxygen content can determine the size of insects.
Question: Which of the following, if true, would best support the above argument?
 A. Studies of invertebrates in the ocean have also found that in colder water and with higher oxygen content, the organisms there are also larger
 B. During the Carboniferous period, the concentration of oxygen in the earth ’s atmosphere was as high as 35%, much higher than the current 21%.At that time, there were many giant insects on the earth, and the wingspan of the dragonfly was close to one meter.
 C. Small locusts cannot survive in a low-oxygen environment, especially in an environment with an oxygen concentration below 15%.Adult locusts can survive in an environment with 2% oxygen
 D. Under the environment with high oxygen content and high air pressure, the tested fruit flies lived to the fifth generation and their body size increased by 20%
