Article: Inside the pleasingly fragrant cafe, So All May Eat(SAME) in downtown Denver ,the spirit ofgenerosityis instantly noticeable :donation box stands in place of a cash register. Customers here pay only what they can afford, no questions asked.A risky business plan, perhaps, but SAME Cafe has done one unchangeable thing in the Mile High City for six years: Open only at midday, the restaurant allows poor local customers who cannot pay to work as volunteers instead. They can act as waiters and waitresses, and dishwashers, or look after the buildings and equipment for the cafe. It's based on trust, and it's working all right", says co-owner Brad Birky, who started the cafe in 2006. Previously volunteering at soup kitchens, the Birkys were dissatisfied with the often unhealthy meals they served there. "We wanted to offer quality food in a restaurant where everyone felt comfortable, regardless of their circumstances," Birky says. SAME's special lunch menu changes daily and most food materials are natural and grown by local farmers. The cafe now averages 65 to 70 customers (and eight volunteers) a day. And the spirit of generosity behind the project appears to be spreading. In early 2007,one volunteer who had cleared snow for his meals during t he long winter said goodbye to the Birkys, He said he was going to New Orleans to help with the hurricane clearing up," says Birky. Question: According to the passage, which of the following is TRUE? - The customers who cannot pay can work as volunteers instead. - More volunteers will go to new Orleans for the hurricane cleanup. - Many new cafes will be opened to offer free lunches in the town. - The lunch menu has remained the same since the cafe was started.
The customers who cannot pay can work as volunteers instead.

One solution to this problem is to put the drugs inside a capsule, protecting them from the body--and the body from them--until they can be released at just the right spot. There are lots of ways to trigger this release, including changing temperature, acidity, and so on. But triggers can come with their own risks--burns, for example. Now, researchers in California have designed what could be a harmless trigger to date: shining near-infrared light (NIR, ) on the drug in the capsule. The idea of using light to liberate the drug in the capsule isn't new. Researchers around the globe have developed polymers and other materials that begin to break down when they absorb either ultraviolet (UV, ) or visible light. But tissues also readily absorb UV and visible light, which means the drug release can be triggered only near the skin, where the light can reach the capsule. NIR light largely passes through tissues, so researchers have tried to use it as a trigger. But few compounds absorb NIR well and go through chemical changes. That changed last year when Adah Almutairi, a chemist at the University of California, San Diego, reported that she and her colleagues had designed a polymer that breaks down when it absorbs NIR light. Their polymer used a commercially available NIR-absorbing group called o-nitrobenzyl (ONB). When they catch the light, ONB groups fall off the polymer, leading to its breakdown. But ONB is only a so-so NIR absorber, and it could be poisonous to cells when it separates from the polymer. So Almutairi and her colleagues reported creating a new material for capsules that's even better.This one consists of a long chain of compounds called cresol groups linked in a polymer. Cresol contains reactive components that make it highly unstable in its polymeric form, a feature Almutairi and her colleagues use to their advantage. After polymerizing the cresols, they cap each reactive component with a light-absorbing compound called Bhc. When the... Question: Why is ONB unsatisfactory? - It breaks down when it absorbs NIR light. - It falls off the polymer and triggers drug release. - It has not come onto the market up till now. - It is not effective enough and could be poisonous.
It is not effective enough and could be poisonous.

Q: Read the following article and select the best answer. Article: Here are some of the strangest buildings in the world. Please look at them and tell us your impressions. Stone House, Portugal The stone house in Portugal is really similar to the famous home of the Flintstones (<<>> ). It is built between two rocks and its architecture has impressed some of the greatest architects. The house was attacked by some bad people. The house is pretty comfortable inside, with a fireplace and every- thing necessary, so it is a wonderful example of modern architecture in Stone Age style! Dancing Building, Czech Republic The Dancing House, or "Fred and Ginger", is situated in Prague, the Czech Republic. It is an amazing masterpiece of architecture which has its own romantic charm. There is something so sweet in the way the buildings hug each other for a dance! It has become a symbol of the city! The Crooked House, Poland The crooked house in Poland has an extraordinary and amazing structure. It was built in 2003 with its design based on the pictures of Jan Marcin Szancer and Per Dahlberg. It looks as if it has been taken from a cartoon: its design is "crooked", but it is balanced, so it is not ugly at all, just strange! The interesting part is how builders managed to create this genius idea, but the house is a fact and everyone admires their creativity! Habitat 67, Montreal, Canada Habitat 67 in Canada is a very interesting arrangement of cubes,which looks like the building blocks that children play with. It is pretty interesting how it was designed -- it looks so original, and at the same time the building is completely stable and comfortable for living! It was created as a main attraction for Expo 67, where it was officially exposed! Question: What is a special feature of The Crooked House? - It was designed by two architects. - It has the longest history of the four. - Its construction lines are not straight. - Its design inspiration is from cartoons.
A: Its construction lines are not straight.
