The nineteenth century brought with it a burst of new discoveries and inventions that revolutionized the candle industry and made lighting available to all. In the early-to-mid-nineteenth century, a process was developed to refine tallow (fat from animals) with alkali and sulfuric acid. The result was a product called stearin. Stearin is harder and burns longer than unrefined tallow. This breakthrough meant that it was possible to make tallow candles that would not produce the usual smoke and rancid odor. Stearins were also derived from palm oils, so vegetable waxes as well as animal fats could be used to make candles . . . “
Which of the following can be inferred from paragraph 1 about candles before the nineteenth century?
Paragraph 5:The Whigs, in contrast, viewed government power positively. They believed that it should be used to protect individual rights and public liberty, and that it had a special role where individual effort was ineffective. By regulating the economy and competition, the government could ensure equal opportunity. Indeed, for Whigs the concept of government promoting the general welfare went beyond the economy. In particular, Whigs in the northern sections of the United States also believed that government power should be used to foster the mora借貸,l welfare of the country. They were much more likely to favor social-reform legislation and aid to education.
Which of the following can be inferred from paragraph 5 about variations in political beliefs within the Whig Party? (4)
○They were focused on issues of public liberty.
○They caused some members to leave the Whig party.
○They were unimportant to most Whigs.
○They reflected regional interests.
通读题干和文章段落以后，咱们来阐发选项。
第一个选项They were focused on issues of public liberty，意思是他们集中存眷公家自由的问题。这个选项和文章第一句话They believed that it should be used to protect individual rights and public liberty抵牾，原辞意思是他们信赖它应当被用来庇护小我权力和公家自由。故解除。
第二个选项They caused some members to leave the Whig party，意思是他们造成为了一些成员分开了辉格党。这属于第三类毛病，和文章没啥瓜葛，整段也没有雷同的意思呈现。故解除。
第三个选项They were unimportant to most Whigs。这个选项也是和文章信息没有瓜葛的，整段并无提重不首要如许的信息。故解除。
以是准确谜底是第四个选项，定位句是In particular, Whigs in the northern sections of the United States also believed that government power should be used to foster the moral welfare of the country.经由过程正常的揣度总结可知，政治信奉的多样性确切影响了地域的长处，对应定位句中的Whigs in the northern sections of the United States，美国北部的辉格党这个信息。
再来一个例题：
Paragraph 2: Hills and mountains are often regarded as the epitome of permanence, successfully resisting the destructive forces of nature, but in fact they tend to be relatively short-lived in geological terms. As a general rule, the higher a mountain is, the more recently it was formed; for example, the high mountains of the Himalayas are only about 50 million years old. Lower mountains tend to be older, and are often the eroded relics of much higher mountain chains. About 400 million years ago, when the present-day continents of North America and Europe were joined, the Caledonian mountain chain was the same size as the modern Himalayas. Today, however, the relics of the Caledonian orogeny (mountain-building period) exist as the comparatively low mountains of Greenland, the northern Appalachians in the United States, the Scottish Highlands, and the Norwegian coastal plateau.
Which of the following can be inferred from paragraph 2 about the mountains of the Himalayas? （2）
○Their current height is not an indication of their age.
○At present, they are much higher than the mountains of the Caledonian range.
○They were a uniform height about 400 million years ago.
○They are not as high as the Caledonian mountains were 400 million years ago.
一样的，读完题干和段落以后，咱们来阐发选项。
选项一Their current height is not an indication of their age. 意思是Himalayas山今朝的高度不是他们年数的批示。这个选项较着与文章信息抵牾。As a general rule, the higher a mountain is, the more recently it was formed;和Lower mountains tend to be older，这些信息都阐明山的高度和他们的额年数是有必定的瓜葛的。故解除。
选项三They were a uniform height about 400 million years ago.经由过程文章这句话for example, the high mountains of the Himalayas are only about 50 million years old可知，Himalayas山在400 million years ago尚未呈现，以是这个选项属于文章抵牾信息，故解除。
选项四They are not as high as the Caledonian mountains were 400 million years ago.这个选项较着与文章中About 400 million years ago, when the present-day continents of North America and Europe were joined, the Caledonian mountain chain was the same size as the台北當舖, modern Himalayas这句话抵牾，故解除。
