In paragraph 6, why does the author discuss Earth' s magnetic field?

Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information[ Paragraph 6] There is further evidence that Earth may have a metallic core. Anyone who understands the functioning of a compass is aware t hat Earth has a magnetic field. The planet itself behaves as if there was a great bar magnet embedded within it. A magnetic field is developed by the flow of electric charges and requ ires good electrical conductors. Silicate rocks, such as those in the mantle and crust, do not conduct electricity very well, whereas metals such as iron and nickel are good conductors. Heat-driven movements in t he outer core, coupled with movements induced by Earth' s spin, are thought to provide the necessary flow of electrons (very small particles that carry a negative charge) around the inner core that produces the magnetic field. Without a metallic core, Earth' s magnetic field would not be possible.

Paragraph 4 suggests which of the following about books in Britain?

Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.[ Paragraph 4 ] Cheap print was public policy in America. While European governments taxed newspapers and other publications, the United States let them go tax free and even subsidized them, to a degree, through the postal system. The rise of cheap books and other forms of cheap print in the United States also reflected distinctive patterns of nineteenthcentury American consumer markets. As the economic historian Nathan Rosenberg remarks, citing the cases of cutlery, guns, boots, and clothing, "Americans readi ly accepted products which had been deliberately designed for low cost, mass production methods" at a time when handmade goods persisted in Britain Books fit this pattern. Americans had not been primarily responsible for introducing new manufacturing technology to the production of books. On the contrary, most of the key advances in printing and papermaking before 1850 had traveled west across the Atlantic rather than the reverse. But t he industrialization of book production proceeded more rapidly in t he United States, where t he market by t he middle decades of the century was not only larger than in Britain but also apparently more sensit ive to price t han to quality, perhaps because elite readers const ituted a smaller proport ion of book buyers.
