In 2022, the Mars rover Curiosity captured an image of a certain area on the Martian surface. Compared to an image taken four years earlier at the same location, new gullies and signs of mudflow were observed. Based on this, some scientists inferred that these new landforms prove the existence of liquid water activity on the surface of Mars to this day.
Which of the following, if true, would most weaken the scientists' inference above? A
(A) Variations in Martian surface temperatures can lead to similar landform changes without the involvement of liquid water. 在Martian表面温度的变化可以在没有水的情况下造成相似的地貌变化，他因削弱
(B) Several small-scale Martian dust storms have occurred in the area over the past four years. 在过去的四年里，该地区发生了几次小规模的火星沙尘暴，无关选项
(C) Similar new landforms have also been discovered by rovers in some other regions of Mars. 探测器在M其他相似地区也发现了新地貌。其他地区，排除
(D) The presence of liquid water is a sufficient but not necessary condition for rapid landform changes on the Martian surface. 液态水的存在是充足的，但不是在M上地貌迅速改变的必要条件
(E) Movements in the Martian lithosphere can trigger earthquakes, causing landslides that leave new traces on the surface. Ml的运动诱发了地震，在地表留下了新痕迹

Premise: 同一个位置，发现了新的沟壑和泥石流的现象
Conclusion: 这些新地貌证明了水存在于火星上
题型：削弱题，削弱科学家认为水存在于火星上













Compared to large water treatment plants, small water treatment plants have weaker purification capabilities, resulting in higher levels of impurities in the water, which can lead to a higher incidence of illness among those who drink it. In a certain city, the newly added population all consume water from small water treatment plants, thus increasing the proportion of people drinking water from these plants. Therefore, the proportion of the population falling ill is also likely to rise.
Which of the following, if true, would most weaken the argument above?  D
(A) The majority of the city's population continues to consume water from large water treatment plants. 该市的大多数人口继续使用大型水处理厂的水，无关选项，排除
(B) The city has implemented stricter regulations on water quality for all water treatment plants.
(C) The newly added population previously consumed untreated well water before moving to the city. 与之前的健康状况无关
(D) Small water treatment plants have been upgrading their purification technologies to match those of large plants. 直接提到了小处理厂的净化问题，所以当净化问题得到改善时，人就不容易生病
(E) The incidence of illness among the city's population has remained stable over the past few years.

Premise: 小型水处理厂的净化能力比大型水处理厂差，会导致疾病发生率更高。新增人口全部用的是所有从小净化水厂处理的水，增加了喝小型净化水厂的比例
Conclusion: 得病人数比例可能上升

CR，答题卡：AD，答案：AD
1. P：火星观测点最新传回图片能看到有gullies and muflow
C：这证明火星表明有液体水活动
削弱题，立场：并不能证明火星表面有液体水活动
逻辑链条：有别的因素（它因）使得火星表面看起来有mudflow，而不是液体水产生的mudflow
答案A：火星表面的温度变化导致其产生相似的地表形态，在没有液体水的情况下。【表明没有水也能产生这个形态】

2. P：比起大水厂，小水厂过滤设备不行，有杂质，容易导致喝小水厂的人生病。这个城市里的新来的人口都是喝小水厂的水
C：生病的人比例会增加
削弱题，立场：生病的人的比例不会增加
逻辑链条：有别的因素（它因）使得其结果改变
答案D：小水厂已经升级了设备技术和大水厂一样【直接削弱题目中说的小水厂的技术问题】

CR
我的答案:A；火星漫游者拍了一个新照片，跟四年前同一位置的照片有不同；据此，科学家认为火星上有水；---哪个为真，削弱---A 其它编号也会引起相似的地貌改变，不需要水；D 水的存在是充分条件，不是必要条件，引起火星地貌快速的改变；
我的答案：D；大水厂比小水厂的过滤系统更好，所以小水池的水更容易让人生病；一个城市，新增加的人口都是喝小水厂的水，所以这个城市生病人数的比例也会相应增加；---哪个为真，削弱---D 小水厂升级技术，使水质量跟大厂一致；
