Archaeology as a profession faces two major problems. First, it is the poorest of the poor. Only paltry sums are available for excavating and even less is available for publishing the results (5) and preserving the sites once excavated. Yet archaeologists deal with priceless objects every day. Second, there is the problem of illegal excavation, resulting in museum-quality pieces being sold to the highest bidder. (10) Iwould like to make an outrageous suggestion that would at one stroke provide funds for archaeology and reduce the amount of illegal digging. Iwould propose that scientific archaeological expeditions and governmental (15) authorities sell excavated artifacts on the open market. Such sales would provide substantial funds for the excavation and preservation of archaeological sites and the publication of results. At the same time, they would break the illegal (20) excavator's grip on the market, thereby decreasing the inducement to engage in illegal activities. You might object that professionals excavate to acquire knowledge, not money. Moreover, ancient artifacts are part of our global cultural heritage, (25) which should be available for all to appreciate, not sold to the highest bidder. Iagree. Sell nothing that has unique artistic merit or scientific value. But, you might reply, everything that comes out of the ground has scientific value. Here we part company. (30) Theoretically, you may be correct in claiming that every artifact has potential scientific value. Practically, you are wrong. I refer to the thousands of pottery vessels and ancient lamps that are essentially duplicates of (35) one another. In one small excavation in Cyprus, archaeologists recently uncovered 2,000 virtually indistinguishable small jugs in a single courtyard. Even precious royal seal impressions known as I'melekh handles have been found in abundance (40) —more than 4,000 examples so far. The basements of museums are simply not large enough to store the artifacts that are likely to be discovered in the future. There is not enough money even to catalog the finds; as a result, they 368 (45) cannot be found again and become as inaccessible as if they had never been discovered. Indeed, with the help of a computer, sold artifacts could be more accessible than are the pieces stored in bulging museum basements. Prior to sale, each could be (50) photographed and the list of the purchasers could be maintained on the computer. A purchaser could even be required to agree to return the piece if it should become needed for scientific purposes. It would be unrealistic to suggest that illegal (55) digging would stop if artifacts were sold on the open market. But the demand for the clandestine product would be substantially reduced. Who would want an unmarked pot when another was available whose provenance was known, and that was dated (60) stratigraphically by the professional archaeologist who excavated it? The primary purpose of the passage is to propose (A) an alternative to museum display of artifacts (B) a way to curb illegal digging while benefiting the archaeological profession (C) a wayto distinguish artifacts with scientific value from those that have no such value (D) the governmental regulation of archaeological sites (E) a new system for cataloging duplicate artifacts

请唐瑭老师答疑：这道题最后一句划定的范围是hunt和A数量的关系，BCD能够自己排除，A项说人口增加，我觉得人口增加不一定hunt就会增加再影响人口，所以无关，但E项，A在人少的场合被目击的次数多，不就代表A多了是因为那里人少，hunt肯定是人来完成的，人少就少有hunt。

请唐瑭老师答疑： 我的思路是：原文最后一句划定的范围是对于延误来说，天气等不可控因素是一部分，但可控因素是有明显下降的，大致就是延误的因素。可以排除BCE选项，A选项低估airline error的占比，而D项，不可控因素在上升，为什么A错误而D正确呢？谢谢老师！

请唐瑭老师答疑：请唐老师用他的思路讲一下这道题。谢谢老师！

请唐瑭老师答疑：还不太能够理解为什么选D选项，能讲下这道题嘛，想知道是不是从一开始思路就错了。谢谢老师！

请唐瑭老师答疑：这个题可以不用看原文，直接在题干中总结范围：suncrop追求less profit，C项中cattle ranching高税的profits会产生比其他工业的profits更高，而E项中，开展RT的成本要比开展CR的成本高，对profit来说中间还有一步推理

请徐小梅老师答疑：

1.问题1 一个数的余数问题额，怎么看他除以248395的余数他的余数是与他各个位数上的和加起来除以这几个数的余数相等么？ 2.在质因数分解中，为什么每个分解出的质数的幂+1相乘等于他质数的个数，能解释一下原理吗？

没有找到这个细节题在哪里，好像没有怎么理解文章的意思。文章是在讲biologist和historian的explanation的方式以及biologist是以historian explaination为基础，然后发现了一些漏洞吗？ 希望张老师回答一下🥺

请教一下小梅老师，在用间接法时 所有情况-相邻捆绑=两个I没有挨在一起的情况 我的笔记上写的所有情况的表达式是C25A33 但现在自己看不懂了，希望老师讲下为什么

这题E选项是对的，但consumers主语后面谓语动词为什么是一般现在时，整个句子不是过去式么？
