It is easy to find your way around it too. And busy people, notice this, Mrs Fry tells you how much time you need in order to get each dish ready. Quick Cooking has four parts, one for each season. This helps you to use fresh fruit and vegetable when they are cheaper--and, of course, better. There are a lot of exciting ideas from foreign countries, and most of the recipes are easy to follow. You take something simple like a chicken or some cheese, and make an unusual dish out of it. For example, there are no fewer than 40 recipes for eggs! Mrs Fry does not plan complete meals for the "quick book". The beginners will have to find out a lot of things for himself or herself. But this ought to be difficult with such a good book. I wanted to try many of the recipes as soon as I read them. For people with little spare time, Helen Fry's Quick Cooking is excellent value.

(Question)
Read the following article and select the best answer. Article: This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu oil mixed with 80% conventional jet fuel. What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions from airplanes. there are a lot of hurdles that still need to be overcome. First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet'A'fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same. The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter - the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up. However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae produced in sewage treatment plants, not from food sources. Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel-a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project. While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen! Question: .Why does Virgin Airlines try to replace normal fuel with biofuel? - To cut down the flight cost of the company. - To remove some hurdles for the biofuel to work. - To reduce CO 2 emissions from airplanes. - To test plane engines on biofuel.
(Answer)
To reduce CO2 emissions from airplanes.

Ques:Read the following article and select the best answer. Article: When most of us look at our hands, we might notice that we need to clean, or stop biting our fingernails, and that's about it. But if you ask a doctor, he can see a whole lot more. Everything from poor diet and stress to serious kidney problems can be revealed by a glance at your fingernails. There are about 30 different nail signs that can be associated with medical issues, though may indicate more than one problem, according to Dr.Amy Derick, a clinical instructor of dermatology at Northwestern University. Here are five of the things a doctor can tell about your health based on your fingernails. 1. People who aren't eating well and lack vitamin or dietary may have thinner than normal nails, which are more likely to break. 2.Horizontal lines are associated with serious physical stress. They frequently occur in people who have gone through chemotherapy .They can also occur after some illnesses, injuries, or with severe malnourishment .Interestingly, there may be an altitude connection too. They've also been found in people who dove 1,000 feet and others who participated in an Everest exploration. 3. Vertical lines, however, are generally not such a big deal. Some people are more genetically prone to them than others, but they're commonly associated with aging. 4. When people lack iron, their nails can turn spoon-like. Instead of curving down and covering the finger normally, they 'll start to rise up on the sides and front, like the part of a spoon that holds liquid. 5. Kidney and liver problems can create "half-and-half nails", where one part of the nail is white and the other part dark or pink, according to Derick. Doctors note that because disease diagnosis is complex and some symptoms can be associated with different diseases, you should always see a medical professional if you are concerned about something you notice. Question: Who will have horizontal lines on the nails ? - A cancer patient who has received normal treatment. - Hungry African children suffering from severe malnourishment. - An explorer who had reached Zhangjiajie in Hunan Province. - A patient with serious illness, like kidney and liver problems.

Ans:
Hungry African children suffering from severe malnourishment.
