Read the following article and select the best answer. Article: A food additive is any substance that is added to food. Many people are put off by the idea of "chemicals in food". The truth is that all food is made up of chemicals. Natural substances like milk, as well as man-made ones like drinks on sale in the market, can be described by chemical formulas . Some chemical substances are indeed harmful, but a person who refused to consume any chemicals would find nothing to eat. The things we eat can be divided into natural and man-made substances. Some people feel that only natural foods are healthy and that all man-made ingredients are to be avoided. But many natural chemicals, found in plants and animals, are harmful when eaten, and some laboratory----made substances increase the nutritional value of food.Other chemicals have natural and man-made forms that are exactly alike: vitamin C is vitamin C, whether it comes from a test tube or from an orange.Like "chemical", "man-made" doesn't necessarily mean "not fit to eat". Food additives are used for many reasons. We add sugar and salt and other things to foods we prepare at home to make them taste better. Food producers have developed a range of additives that stabilize, thicken, harden, keep dry, keep wet, keep firm, or improve the appearance of their products. Additives can make food more convenient or nutritious, give it a longer shelf life, and make it more attractive to the consumer, thus increasing the sales and profits of the producers. Food additives are presently the centre of a storm of serious argument. Food producers have been known to use additives that have not been proved safe; some substances in common use have been proved unsafe and have been taken off the market. Many people feel there's a risk of eating food to which anything has been added. But food additives are now regulated by the FDA of the federal government, and new additives are subjected to strict testing before they can be placed on the market. For most people, the chances of developing serious side effects from the long-term use of... Question: We can infer from the regulation to the food additives by the FDA that _ . - new additives will be approved more easily than before - food producers won't be allowed to use new food additives - food with common-used additives will be taken off the market - food additives will be used in a safer and more scientific way
food additives will be used in a safer and more scientific way

Q: Read the following article and select the best answer. Article: You're not doomed to toss and turn every night. Although you might not be able to control all of the factors that relate to your sleep, you can adopt habits that encourage better sleep. Start with these simple sleep tips. No. 1: Stick to a sleep schedule Go to bed and get up at the same time every day, even on weekends, holidays and days off. Being consistent reinforces your body's sleep-wake cycle and helps promote better sleep at night. If you don't fall asleep within about 15 minutes, get up and do something relaxing. Go back to bed when you're tired. No. 2: Pay attention to what you eat and drink Don't go to bed either hungry or stuffed. Your discomfort might keep you up. Also limit how much you drink before bed, to prevent disruptive middle-of-the-night trips to the toilet. Nicotine, caffeine and alcohol deserve caution, too. The stimulating effects of nicotine and caffeine -- which take hours to wear off -- can ruin quality sleep. No. 3: Create a bedtime ritual Do the same things each night to tell your body it's time to wind down. This might include taking a warm bath or shower, reading a book, or listening to light music. Be careful of using the TV or other electronic devices as part of your bedtime ritual. Some research suggests that screen time or other media use before bedtime has impact on sleep. No. 4: Get comfortable Create a room that's ideal for sleeping. Often, this means cool, dark and quiet. Consider using room-darkening shades, earplugs, a fan or other devices to create an environment that suits your needs. Your mattress and pillow can contribute to better sleep, too. Since the features of good bedding are subjective, choose what feels most comfortable to you. If you have children or pets, set limits on how often they sleep with you -- or insist on separate sleeping quarters. No. 5: Limit daytime naps Long daytime naps can affect nighttime sleep -- especially if you're struggling with poor sleep quality at night. If you choose to nap during the day, limit yourself to about 10 to 30... Question: According to the passage, in what situation do you need to contact your doctor? - You can not nap in the day time. - You frequently have trouble sleeping. - You do not fall asleep within 15 minutes. - You have too much to think about before bed.
A: You frequently have trouble sleeping.

(Q).
Read the following article and select the best answer. Article: Shundagarh is a village on India's east-facing coast.It is a village of simple mud and grass houses built on the beach just above the waterline.The Khadra Hills rise immediately behind the village,to a height of one hundred and fifty meters.A simple,good-hearted old man,whose name was Jalpur,farmed two small fields on the very edge of these hills.From his fields he could see the fishing boats that travelled up and down the coast.He could see the children playing on the sands;their mothers washing clothes on the flat stones where the Shiva River flowed into the sea;and their fathers landing the latest catch or repairing nets and telling stories that had no end. All Jalpur owned in the world were the clothes he wore day in and day out,the miserable hut that he slept in at night,a few tools and cooking pots--and his fields.The corn that he grew was all that made life possible.If the weather was kind and the harvest was good,Jalpur could live happily enough--not well,but happily.When the sun was fierce,and there was little or no rain,then he came close to the line between life and death. Last year the weather had been so kind,and the harvest promised to be so good,that Jalpur had been wondering whether he could sell all that he had and live with his son farther up the coast.He had been thinking about doing this for some years.It was his dearest wish to spend his last days with his son and his wife.But he would go only if he could give;he would not go if it meant taking food out of the mouths of his grandchildren.He would rather die hungry than do this. On the day when Jalpur decided that he would harvest his corn,sell it,and move up the coast,he looked out to sea and saw a huge wave,several kilometers out,advancing on the coast and on the village of Shundagarh.Within ten minutes everyone in Shundagarh would be drowned.Jalpur would have shouted,but the people were too far away to hear.He would have run down the hill,but he was too old to run.He was prepared to do anything to save the people of Shundagarh,so he... Question: Which of the following could Jalpur NOT see from his Fields? - Mothers washing clothes. - Fathers taking their corn to market. - Fishing boats traveling on the sea. - Children playing on the sands.
