大家帮我解解惑吧，THANKS！~ in swartkans territory,archaeologists discovered charred bone fragments dating back 1 million years. aanalysis of the fragments,which came from a variety of animals,showed that they has been heated to temperatures no higher than those produced in experimental campfires made from branches of white stinkwood,the most common tree around swartkans.
which of the following,if true,would together with the information above,provide the best basis for the claim that the charred bome fragments are evidence of the use of fire by early hominids?
e the bone fragments were found in several distinct layers of limestone that contained primitive cutting tools known to have been used by early hominids.
不知道答案这个cutting tool和fire有什么关系啊？
it is very difficult to prove today that a painting done two or three hundred years ago, especially one without a signature or with a questionably authentic signature, is indubitably the work of this or that particualr artist. this fact gives the traditional attribution of a disputed painting special weight,since that attribution carries the presumption of historical continuity. consequently, an art historian arguing for a deattribution will generally convince other art historians only if he or she can persuasively argue for a specific reattribution.
which of the following,if true, most strongly supports the position that the traditional attribution of a disputed painting should not have special weight?
a art dealers have always been led by economic self-interest to attribute an unsigned paintings of merit to recognized masters rather than to obscure artists.
我想问问大家这种很长而且逻辑关系感觉不是很明显的题目，大家怎么读题的？
television programing experts maintain that with each 1% increase in the prime -time ratings of a television station there is a 3.5% increase in the number of people who watch its evening news program.however,in the last ten years at channel ntr,there was only one year of extremely high prime-time ratings and during that year,fewer people than ever watched channel ntr's evening news program.
which of the following conclusions can properly be drawn from the statements above?
a when a news program has good ratings,the channel as a whole will have good ratings. b the programming experts neglected to consider daytime news programs.
c the year of high ratings at ntr was a result of two hit shows which were subsequently canceled because of contractual problems
d the ten-year period in question is not representative of normal viewing patterns. e prime-time ratings are not the only factor affecting how many people watch an evening news program.
原文中有提到they has been heated to temperatures no higher than those produced in experimental campfires made from branches of white stinkwood。有cutting tool说明可能当时的原始人类使用cutting tool采伐white stinkwood来生火。
