Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question. Plastic bags are used by everybody. From a vegetable vendor to a designer store, everyone seems to use them. Even though they are one of the modern conveniences that we seem to be unable to do without, they are responsible for causing pollution, killing wildlife, and using up the precious resources of the Earth. But, most of us are blissfully unaware of the repercussions that are occurring and will take place in the future because of the plastic bags. Every once in a while, the government passes out an order banning store owners from providing plastic bags to customers for carrying their purchases, with little lasting effect. Plastic bags are very popular with both retailers as well as consumers because they are cheap, strong, lightweight, functional, as well as a hygienic means of carrying food as well as other goods. About a hundred billion plastic bags are used every year in the U.S. alone. And then, when one considers the huge economies and populations of India, China, Europe, and other parts of the world, the numbers can be staggering. The problem is further exacerbated by the developed countries shipping off their plastic waste to developing countries like India. Once they are used, most bags go into landfills. Each year, more and more bags are ending up littering the environment. Once they become litter, plastic bags find their way into our waterways, parks, beaches, and streets. And, if they are burned, they infuse the air with toxic fumes. About 100,000 animals, such as dolphins, turtles, whales, penguins are killed every year due to these bags. Many animals ingest plastic bags, mistaking them for food, and therefore, die. And worse, the ingested plastic bag remains intact even after the death and decomposition of the animal. Thus, it lies around in the landscape where another victim may ingest it. One of the worst environmental effects is that they are non-biodegradable. The decomposition takes about 400 years. No one will live so long to witness the decomposition of plastic! Thus, save the environment for the future generations as well as animals. Petroleum products are diminishing and getting more expensive by the day, since we have used this non-renewable resource increasingly. And to make plastic, about 60-100 million barrels of oil are needed every year around the world. Surely, this precious resource should not be wasted on producing plastic bags, should it? Petroleum is vital for our modern way of life. It is necessary for our energy requirements - for our factories, transportation, heating, lighting, and so on. Without viable alternative sources of energy yet on the horizon, if the supply of petroleum were to be turned off, it would lead to practically the entire world grinding to a halt. So, what can be done? A tote bag can make a good substitute for carrying groceries and the shopping. You can keep the bag with the cashier, and then put your purchases into it instead of the usual plastic bag. Recycling the bags you already have is another good idea. These can come into use for various purposes, like holding your garbage, instead of purchasing new ones. While governments may be working out ways to lessen the impact of plastic bags on the environment; however, each of us should shoulder some of the responsibility for this problem, which ultimately harms us. Plastics are not only non-biodegradable, but are one of the major pollutants of the sea. For a clean and green environment, try to use alternatives to plastic whenever and wherever possible. Cut down your use of plastic, and do your bit to save our planet.                                                                                                    (Source: https://helpsavenature.com/) Which of the following could be the best tittle of the passage?

Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question. Some doctors think that you should drink a glass of water each morning. You should drink this water first thing, before doing anything else. The temperature of the water should be similar to body temperature; neither too hot nor too cold. Why should you drink this water? Water helps your body in many ways. It helps clean out your kidneys. It prepares your stomach for digestion. Water can also help your intestines work better. After drinking water, the intestines can more easily take out nutrients from our food. Water also helps us go to the bathroom more easily. Scientists suggest that people take in 1,600 milliliters of water each day. But don’t drink all of that water in one sitting. If you do, your kidneys will have to work much harder to eliminate it. It’s better to drink some in the morning and some in the afternoon. Some people think it’s better to drink between meals and not during meals. They think water dilutes the juices produced in our stomachs. This can interfere with normal digestion. Are you drinking enough water every day? Check the color of your urine. If it is light yellow, you are probably drinking enough. If your urine is very dark yellow, you probably need to drink more water. A little more water each day could make you much healthier.                                      (Adapted from Reading Challenge 1 by Casey Malarcher and Andrea Janzen) What is the main idea of the passage?
