Quoting an article in New Scientist magazine, Cleary said that the role of memory is not necessarily to remember the past, but to help us move into the future. Memory sometimes uses imagination and creation to let us know what to do next, or how to react in certain situations. Some people think that they have the ability to foresee the future, but they may be fragmented memories of the past. If the feeling of deja vu comes from an unremembered memory, it is easy to create the illusion that what happens next also comes from this memory and that you have "psychic abilities".

Question: Which of the following options is inconsistent with the above point of view?

Choices:
- A.Deja vu is not "psychic ability".
- B.Deja vu can help us see the future.
- C.Deja vu is an incomplete memory of the past.
- D.People's memories are not necessarily memories of the past.


Most galaxies are moving away from us, and their receding speed (redshift) is proportional to the distance of the galaxies. This proportional coefficient, now known as the Hubble constant, represents the current rate of expansion of the universe. One of the core tasks of observational cosmology is to measure the relationship between distance and redshift. it describes the history of cosmic expansion, answers basic questions about the age, geometry and composition of the universe, and even tests many new physical predictions. In astronomical observations, the redshift of distant celestial bodies can be accurately obtained, but the accurate measurement of distance has always been the biggest problem for astronomers.

Question: Which of the following options is most likely to be discussed by the author next?

Choices:
- A.How astronomers accurately measure distance .
- B.How astronomers accurately measure redshift.
- C.Difficulties encountered in the measurement of distances.

In other words, human beings can achieve maximum action power by obtaining a small amount of energy at 37 °C. As a result, 37 °C has been used as a standard of body temperature for human health for more than a century.

Phosphorus exists in our DNA and is one of the basic elements that make up life. But how it reached Earth in its early days remains a mystery. Recently, scientists have tracked the "journey" of phosphorus-containing molecules from the universe to Earth by observing  regions where stars form. The observations show that phosphorus-containing molecules are produced during the formation of massive stars, and the newly formed stars release airflow, creating a channel in the interstellar cloud, and as the stars vibrate and release radiation, phosphorus-containing molecules deposit on the walls of these channels and produce a large number of phosphorus monoxide particles, which converge and merge one by one, turning from a small stone into a comet. And these comets became the "messengers" of life, carrying the molecules of life to Earth.

Question: Which of the following options, if true, is the most likely to question the above conclusion?

Choices:
- A.The early impact events of comets brought 10 trillion kilograms of organic matter to the earth every year, which opened the evolution of life on earth after they entered the earth's environment.
- B.Scientists have found evidence in meteorites, and studies have found that a few meteorites carry organic matter that contains phosphorus-containing molecules such as phosphorus monoxide.
- C.When a changing comet hits the earth's surface, it can produce 360000 atmospheric pressure and a temperature of 2500 ℃, which will cause unknown chemical changes in the phosphorus in the comet's crystal.
- D.It is far from enough to have the necessary materials for DNA. Only tens of millions or even hundreds of millions of probability can meet the conditions needed for the formation of life.
