Is it just me that cannot figure why the answers to the following two stimuli are correct?
first one: people today place an especially high value on respect for others; yet, in their comedy acts, many of today's most popular comedians display blatant disrespect for others. But, when people fail to live up to the very ideals they hold in highest esteem, exaggeration of such failings often forms the basis of successful comedy. Thus, the current popularity of comedians who display disrespect in their acts is hardly suprising.
the assumption depends on which of the following:
correct answer: People who value an idea especially highly do not always succeed in living up to this ideal.
2. Brown dwarfs- dim red stars that are too cool to burn hydrogen- are very similar in appearance tp red dwarf stars, which are just hot enough to burn hydrogen. Stars, when first formed, contain substantial amounts of the element lithium. All stars but the coolest of the brown dwarfs are hot enough to destroy lithium completely by converting it to lithium. Accordingly, any star found that contains no lithium is not one of these collest brown dwarfs.
question: the argument depends on assuming which of the following?
correct answer: None of the coolest brown dwarfs has ever been hot enough to destroy lithium.
