It covers seventy-one percent of the earth. There is still much to be discovered about this vast blanket of water. If the waters of the ocean could be removed, the sea floor with its wide valleys, irregular mountains and rivers in the sea would be an unbelievable sight. Tourism under the deep blue sea Tourists can now explore the world beneath the waves without ever getting wet. From tourist submarines to underwater dining, undersea tourism is making a big splash. Tourist submarines The popularity of submarine tours has grown rapidly in the last decade. Now, tourist submarines operate in more than 20 locations worldwide, including the waters around Okinawa and Taiwan's Green Island. The submarines carry nearly 2 million tourists each year. Large windows offer passengers spectacular views as the submarines explore colorful coral reefs and sunken ships. Most one-hour tours cost about US $80. Under water dinning For a more upscale experience, tourists can enjoy fine dining under the sea. Last summer the Hilton Maldives Resort opened the world's first underwater restaurant, Ithaa. Diners walk down a staircase into the restaurant, which rests 35 feet beneath the waves of the Indian Ocean. Transparent walls surround the dining area, and you can treat guests to a panoramic ocean view. But this excellent view doesn't come cheap. The tasting menu costs US $200 per person. Be sure to make reservations early, too. The restaurant seats only 14 people. Question: The walls of the restaurant Ithaa are most probably made of_. Answer:
OPTIONS:
- stone
- brick
- glass
- steel
output: glass

input with options: Read the following article and answer the question. Article: It's not just great minds that think alike. Dozens of the genes involved in the vocal learning that _ human speech are also active in some songbirds . And knowing this suggests that birds could become a standard model for investigating the genetics of speech production and speech disorders. Complex language is a uniquely human trait, but vocal learning -- the ability to pick up new sounds by imitating others -- is not. Some mammals, including whales, dolphins and elephants, share our ability to learn new vocalizations . So do three groups of birds: the songbirds, parrots and hummingbirds. The similarities between vocal learning in humans and birds are not just superficial. We know, for instance, that songbirds have specialised vocal learning brain circuits that are similar to those that mediate human speech. What's more, a decade ago we learned that FOXP2, a gene known to be involved in human language, is also active in "area X" of the songbird brain -- one of the brain regions involved in those specialised vocal learning circuits. Andreas Pfenning at the Massachusetts Institute of Technology and his colleagues have now built on these discoveries. They compared maps of genetic activity in brain tissue taken from the zebra finch, budgerigar and Anna's hummingbird, representing the three groups of vocal-learning birds. They then compared these genetic maps with others taken from birds and primates that can't learn new vocalisations, and with maps taken from the brains of six people who donated tissue to the Allen Brain Institute in Seattle. Their results showed that FOXP2 is just one of 55 genes that show a similar pattern of activity in the brains of humans and the vocal-learning birds. Those same genes show different patterns of activity in the brains of animals incapable of vocal learning. "The similarities are beyond one or a handful of genes," says Pfenning. "There are just systematic molecular similarities between song-learning birds and humans." "There's potential for songbirds to be used to study... Question: What is the passage mainly about? Answer:
OPTIONS:
- Birds have different genes from humans.
- Humans and birds share the same singing genes.
- How FOXP2 affects the brains of humans and birds.
- Experiments with birds can cure the disease of humans.
output: Humans and birds share the same singing genes.

input with options: Read the following article and answer the question. Article: Scientist Says 'No' to Human Cloning "I've never met a human worth cloning," says cloning expert Mark Westhusin from his lab at Texas A&M University. "It's a stupid endeavor." That's an interesting choice of adjective, coming from a man who has spent millions of dollars trying to clone a 13-year-old dog named Missy. So far, he and his team have not succeeded, though they have cloned two cows and a cat. They just might succeed in cloning Missy soon -- or perhaps not for another five years. Westhusin's experience with cloning animals leaves him upset by all this talk of human cloning. In three years of work on the Missy project, using hundreds upon hundreds of dog's eggs, the A&M team has produced only a dozen or so embryos carrying Missy's DNA. None have survived the transfer to a surrogate mother. The wastage of eggs and the many spontaneously aborted(,) fetuses may be acceptable when you're dealing with cats or bulls, he argues, but not with humans. "Cloning is incredibly inefficient, and also dangerous," he says. Even so, dog cloning is a commercial opportunity, with a nice research payoff. Ever since Dolly the sheep was cloned in 1997, Westhusin's phone has been ringing with people calling in hopes of duplicating their cats and dogs, cattle and horses. "A lot of people want to clone pets, especially if the price is right," says Westhusin. Cost is no obstacle for Missy's mysterious billionaire owner; he's put up $3.7 million so far to fund A&M's research. Contrary to some media reports, Missy is not dead. The owner wants a twin to carry on Missy's fine qualities after she does die. The prototype(;)is, by all accounts, athletic, good-natured and supersmart. Missy's master does not expect an exact copy of her. He knows her clone may not have her temperament(, ). In a statement of purpose, Missy's owner and the A&M team say they are "both looking forward to studying the ways that her clones differ from Missy." Besides cloning a great dog, the project may contribute insight into the old question of nature vs.... Question: By "stupid endeavor", Westhusin means to say that _ . Answer:
OPTIONS:
- human cloning is a foolish undertaking
- animal cloning is absolutely impractical
- human cloning should be done selectively
- animal cloning is not worth the effort at all
output:
human cloning is a foolish undertaking
