Ans: Clearing habitats for agriculture
Ques: Habitat destruction is the process in which natural habitat is rendered unable to support the species present. In this process, the organisms that previously used the site are displaced or destroyed, reducing biodiversity. Habitat destruction by human activity is mainly for the purpose of harvesting natural resources for industrial production and urbanization. Clearing habitats for agriculture is the principal cause of habitat destruction. Other important causes of habitat destruction include mining, logging, trawling and urban sprawl. Habitat destruction is currently ranked as the primary cause of species extinction worldwide. It is a process of natural environmental change that may be caused by habitat fragmentation, geological processes, climate change or by human activities such as the introduction of invasive species, ecosystem nutrient depletion, and other human activities.

Based on this passage, what is the main cause of habitat destruction?
CoT: The relevant information to answer the above question is: Clearing habitats for agriculture is the principal cause of habitat destruction.
Answer: 1806. Now, what could be the question and solution-maybe?
Ques: Context: The ability to block a measure through extended debate was an inadvertent side effect of an 1806 rule change, and was infrequently used during much of the 19th and 20th centuries. In 1970, the Senate adopted a "two-track" procedure to prevent filibusters from stopping all other Senate business. The minority then felt politically safer in threatening filibusters more regularly, which became normalized over time to the point that 60 votes are now required to end debate on nearly every controversial legislative item. As a result, the modern "filibuster" rarely manifests as an extended floor debate. Instead, "the contemporary Senate has morphed into a 60-vote institution -- the new normal for approving measures or matters -- a fundamental transformation from earlier years." This effective supermajority requirement has had very significant policy and political impacts on Congress and the other branches of government.

Question: when did the filibuster start in the us senate?
CoT: The relevant sentence in the passage is: The ability to block a measure through extended debate was an inadvertent side effect of an 1806 rule change, and was infrequently used during much of the 19th and 20th centuries.

Ques: Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2 (n) electrons. Since electrons are electrically attracted to the nucleus, an atom's electrons will generally occupy outer shells only if the more inner shells have already been completely filled by other electrons. However, this is not a strict requirement: atoms may have two or even three incomplete outer shells. (See Madelung rule for more details.) For an explanation of why electrons exist in these shells see electron configuration.

Answer this question: what is the maximum number of electrons in the first energy shell of an atom?
CoT: The important part for answering this question is: Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on.
