单选题If the Dakota Access Pipeline (输油管) is completed, it will carry nearly half a million barrels of oil across four states every day. Energy Transfer Partners (ETP), a Texas-based company behind the $3.8 billion project, hopes to finish construction in 20i6. But the Standing Rock Sioux, an American Indian tribe (部落), is determined to stop the 1,172-mile pipeline from being built. （76） Both sides show no signs of backing down. The Dakota Access Pipeline was announced in 2014. A section of it will run near the Standing Rock Sioux reservation. A reservation is an area of land set aside for American Indians. The tribe says the construction threatens to destroy historical areas and ancient burial sites. They also say the pipeline could pollute their main water source, the Missouri River. In April, the standing Rock Sioux began a protest against the project. They camped at the construction site. Since then, thousands of people, including people from other American Indian tribes, have traveled to the site to join the protest. ETP says that the pipeline will have built-in safety measures to protect against oil leaks. Workers will also monitor it remotely, and will be able to close valves (阀) within three minutes if leaks are detected. American Indians have been staging a nonviolent protest for months. The protest took a turn last week when police were called to keep the peace between protesters and armed security guards hired by the company. （77） Twenty-eight people have been arrested since then and charged with interfering with the pipeline construction.

单选题From the goose that laid the golden egg to the race between the tortoise and the hare, Aesop's fables are known for teaching moral lessons rather than literally being true. But a new study says at least one such tale might really have happened. It's the fable about a thirsty crow(乌鸦). The bird comes across a jar with the water level too low for him to reach. The crow raises the water level by dropping stones into the jar. The moral tells: Little by little does the trick, or in other retellings, necessity is the mother of invention. Now, scientists report that some relatives of crows called rooks used the same stone-dropping strategy to get at a floating worm. Results of experiments with three birds were published online by the journbal Current Biology. Rooks, like crows, had already been shown to use tools in previous experiments. Christopher Bird of Cambridge University and a colleague exposed the rooks to a 6-inch-tall clear plastic tube containing water, with a worm on its surface. The birds used the stone-dropping trick naturally and appeared to estimate how many stones they would need. They learned quickly that larger stones work better. In an accompanying commentary, Alex Taylor and Russell Gray of the University of Auckland in New Zealand noted that in an earlier experiment, the same birds had dropped a single stone into a tube to get food released at the bottom. So maybe they were just following that strategy again when they saw the tube in the new experiment, the scientists suggested. But Bird's paper argued there's more to it: The rooks dropped multiple stones rather than just one before reaching for the worm, and they reached for it at the top of the tube rather than trying to reach the food at the bottom. The researchers also said Aesop's crow might have actually been a rook, since both kinds of birds were called crows in the past.
