This is because Scott assumes that rock climbing a wall is the same as Mt. Everest, therefore he is quickly or hastily grouping or generalizing that they are one and the same and the levels of difficulty are also the same. As well as evidence is not accurate and is not logically justified by sufficient evidence.
A - Authority is incorrect as Scott is not declaring authority or ownership over anything or anyone.
C - Popularity is incorrect as Scott is not self-declaring popularity status or anything related to popularity.
D - Slippery Slop is incorrect because Scott is not suggesting that taking a minor action will lead to ludicrous consequences. Although the first half of the statement sounds as if it would be the correct answer, the second half about consequences denotes that as it is merely stating that Scott would be finding a larger consequence as a result rather than an accomplishment.
He totally jumped to conclusions of sorts and is totally not prepared because, while he THINKS climbing Mt. Everest is as simple as this, it's really totally and completely different.
Thunderstorms arise when layers of warm, moist air rise in a large, swift updraft to cooler regions of the atmosphere. There the moisture contained in the updraft condenses to form towering cumulonimbus clouds and, eventually, precipitation.
