In one sentence, describe what the following article is about: . You may be out in the cold for a while to complete this task so be sure to wear warm clothes. You’ll need a waterproof jacket, pants, and boots. Wear gloves to keep your hands warm, as well as a hat to maintain your body temperature.  Wear layers in case you get too warm from the exertion and need to remove an article of clothing. Getting wet can not only make you quite cold, it can also lead to frostbite. Be sure all your outer layers are waterproof! You’ll need a shovel for clearing the area around your car as well as a broom with soft bristles to clear the snow off your car without damaging the paint. You should also bring an ice scraper to clean your windshield and windows.  If you have a snowblower, bring it to make the job a bit easier. You may also want to bring a stepladder if your vehicle is taller than you are, in order to clear snow from the roof. Having lock de-icer on hand is a good idea in case your door locks are frozen shut. Salt can be handy to help melt the snow and ice around your tires, so consider bringing that with you as well. You’ll want firm footing as well as a place to put the snow you remove from your car. Clearing a path first will make the job easier. You could also wait until snow plows come through and clear the area, although sometimes they push more snow along the side of a road where cars may be parked.
Summary: Dress warmly Gather the right tools. Clear a path to your vehicle.

The idea behind multiplication is to shortcut adding the same things over and over again. You use multiplication when you have groups of the same size. For example, maybe you have three cups of water that you drank ten times. How many cups of water did you drink total? You could solve this problem by counting adding the amount of times you drank the water from each cup together, or you could clump them into groups to multiply.   The idea behind division is splitting equal parts into groups. If you have a pizza with eight slices and four friends, how should you split it up so that each person gets an equal amount of the pizza? In division, that problem would be written as eight divided by four. Each person gets two pieces of pizza. For example, order doesn’t matter when you multiply. That’s one of the properties that you should learn if you want to learn multiplication.  You also should learn multiplication problems that change the order of factors, which is called commutativity, problems that change the grouping of factors, which is called associativity. Becoming familiars of the rules to each number will be a huge help when dividing and multiplying. For example, when you multiple numbers by five the answer will always end in a five or a zero. If you multiply a number by two, it will always end in an even number. Similar rules apply for division. Learn these rules and practice your tables.

Problem: Article: Obviously the most important precaution you can take to prevent TB is to avoid being around people with active TB, which is highly contagious, especially if you have already tested positive for latent TB. More specifically:  Don't spend long periods of time with anyone who has an active TB infection, especially if they have been receiving treatment for less than two weeks. In particular, it is important to avoid spending time with TB patients in warm, stuffy rooms. If you are forced to be around TB patients, for example if you work in a care facility where TB is currently being treated, you will need to take protective measures, such as wearing a face mask, to avoid breathing in the TB bacteria. If a friend or family member has active TB, you can help to rid them of the disease and lessen your own risk of contracting it by ensuring that they strictly follow treatment instructions. Certain groups of people are considered to be more at-risk of developing TB than others. If you are a member of ones of these groups, you need to be more vigilant about protecting yourself from TB exposure. Some of the main at-risk groups are as follows:  People with weakened immune system, such as those with HIV or AIDs. People who live with or care for someone with active TB, such as a close relative or a doctor/nurse. Healthcare and social workers who serve high-risk patients, such as people who are homeless. People born where TB is common, including children, and anyone who has immigrated within the last five years from areas that have a high TB rate. People who live in crowded, confined spaces such as prisons, nursing homes, or homeless shelters. People who abuse drugs and alcohol, or have little or no access to proper health care. People who live in or travel to countries where active TB is common, such as countries in Latin America, Africa and parts of Asia . People who are in poor health are more susceptible to the TB virus, as their disease resistance is lower than in healthy people. Therefore, it is important to do your best to lead a healthy lifestyle.  Eat a healthy, balanced diet with plenty of fruit, vegetables, whole grains and lean meat. Avoid fatty, sugary and processed foods. Exercise often, at least three to four times a week. Try to incorporate some good cardiovascular exercise into your workouts, such as running, swimming or rowing. Cut down on alcohol consumption and avoid smoking or taking drugs. Get plenty of good quality sleep, ideally between seven and eight hours a night. Maintain good personal hygiene and try to spend as much time as possible outdoors, in the fresh air. The BCG (Bacille Calmette-Guerin) vaccine is used in many countries to help prevent the spread of TB, especially among small children. However, the vaccine is not commonly used in the US, where infection rates are low and the disease is highly treatable. Therefore, the CDC does not recommend the vaccine as a routine immunization. In fact, the CDC only recommends the BCG vaccine for U.S. citizens in the following situations:  When a child has been tested negative for TB but will continue to be exposed to the disease, especially strains that are resistant to treatment. When a healthcare worker is continually exposed to tuberculosis, especially strains that are resistant to treatment. Before travelling to another country where tuberculosis is prevalent.
Summary:
Avoid exposing yourself to people with active TB. Know if you are "at-risk". Lead a healthy lifestyle. Get the BCG vaccination to prevent TB.
