A.Sales of books by mid-list PRH writers fall off considerably.
B.Lesser-known PRH writers become the target of criticism
C.Waterstones staff hesitate to promote big-name author’s books.
D.Waterstones branches suffer a severe reduction in revenue.
Sales of books by mid-list PRH writers fall off considerably.解析：该题为细节题。根据题干当中的dispute定位到第四段。第二句提到知名PRH作者可能会受到一些影响，但那些通常依赖水石书店员工热情推广不太知名作家作品的中游作家，将会祈祷这场纠纷结束。(it’s those mid-list authors,who normally rely on Waterstones staff’s passion for promoting books by lesser-known writers,who will be praying for an end to the dispute.)。因此能印证居中作家的书籍销量大幅下滑，处于不利地位。故选A。

[A]This year marks the 150th anniversary of a series of Yellowstone photographs by the renowned landscape photographer William Henry Jackson.He captured the first-ever shots of iconic landmarks such as the Tetons,Old Faithful and the Colorado Rockies.Jackson snapped them on a late 19th-century expedition through the Yellowstone Basin that was conducted by the head of the U.S.Geological and Geographical Survey of the Territories,Ferdinand V.Hayden.The team included a meteorologist,a zoologist,a mineralogist,and an agricultural statistician.
<B>Two centuries ago,the idea of preserving nature,rather than exploiting it,was a novel one to many U.S.settlers.One of the turning points in public support for land conservation efforts—and recognizing the magnificence of the Yellowstone region in particular—came in the form of vivid photographs.
[C]As an effective Washington operator,Hayden sensed that he could capitalize on the expedition’s stunning visuals.He asked Jackson to print out large copies and distributed them,along with reproductions of Moran’s paintings,to each member of Congress.“The visualization,particularly those photographs,really hit home that this is something that has to be protected,”says Murphy.
[D]Throughout the trip,Jackson juggled multiple cameras and plate sizes using the collision process that involved coating the plates with a chemical mixture,exposing them and developing the resulting images with a portable darkrooms.The crude technique required educated guesses on exposures times,and involved heavy,awkward equipment--several men had to assist in its transportation.Despite these challenges,Jackson captured dozens of striking photos,ranging from majestic images like his now-famous snapshot of old faithful,to casual portraits of expedition members that the camp.While veterans of previous expeditions had written at length about stunning sights,these vivid photographs were another thing entirely.
[E]The well-documented Yellowstone journey officially began in Ogden,Utah on June 8,1871.Over nearly four months,dozens of men made their way on horseback into Montana and traversed along the Yellowstone River and around Yellowstone Lake.That fall,they concluded the survey in Fort Bridger,Wyoming.
[F]Though Native Americans(and later miners and fur trappers)had long recognized the area’s riches,most Americans did not.That’s why Hayden’s expedition aimed to produce a fuller understanding of the Yellowstone River region,from its hot springs and waterfalls to its variety of flora and fauna.In addition to the entourage of scientists,the team also included artists:Painter Thomas Moran and photographer William Henry Jackson were charged with capturing this astounding natural beauty and sharing it with the world.
[G]The bill proved largely popular and sailed through Congress with large majorities in favor.In quick succession,the Senate and House passed legislation protecting Yellowstone in early 1872.
[H]Perhaps most importantly,these images provided documentary evidence of the park’s sights that later made its way to government officials.Weeks after completing the expedition,Hayden collected his team’s observations into an extensive report aimed at convincing senators and representatives,along with colleagues at government agencies like the Department of the Interior,that Yellowstone ought to be preserved(and that his department deserved additional funds).
首先排除AEH选项，其次，C、D中出现了Jackson非全名，所以排除，F中出现Hayden非全名排除，G the bill表示前面出现过，排除，H perhaps most importantly,these images可知前面出现过images，可排除，答案只能是B。
A中出现The team included……F中出现In addition to the entourage of scientists,the team also……根据逻辑关系可知，F紧跟A后，所以答案是F
D中出现Throughout the trip与E中的The well-documented Yellowstone journey……同义复现。以及D中出现images，H中出现these images。所以答案是D
He asked Jackson to print out large copies and distributed……to each member of Congress.讲到打印出大量得复印品分发给国会，让国会参与。
The bill proved largely popular and sailed through Congress with large majorities in favor.表示保护最后通过国会的议案，进行立法。CG为捆绑选项。
