For formal writing, such as research and argumentative papers, use the third person. Third person makes your writing more objective and less personal. For academic and professional writing, this sense of objectivity allows the writer to seem less biased and, therefore, more credible. Third  person helps the writing stay focused on facts and evidence instead of personal opinion. Third person refers to people “on the outside.” You either write about someone by name or use third person pronouns.  Third person pronouns include: he, she, it; his, her, its; him, her, it; himself, herself, itself; they; them; their; themselves. Names of other people are also considered appropriate for third person use. Example: “Smith believes differently. According to his research, earlier claims on the subject are incorrect.” First person refers to a point of view in which the writer says things from his or her personal perspective. This point of view makes things too personal and opinionated. You should avoid first person in an academic essay.  First person pronouns include: I, me, my, mine, myself, we, us, our, ours, ourselves.  The problem with first person is that, academically speaking, it sounds too personalized and too subjective. In other words, it may be difficult to convince the reader that the views and ideas being expressed are unbiased and untainted by personal feelings. Many times, when using first person in academic writing, people use phrases like "I think," "I believe," or "in my opinion." Incorrect example: “Even though Smith thinks this way, I think his argument is incorrect.” Correct example: “Even though Smith thinks this way, others in the field disagree.” Second person refers to point of view that directly addresses the reader. This point of view shows too much familiarity with the reader since you speak to them directly like you know them. Second person should never be used in academic writing.  Second person pronouns include: you, your, yours, yourself.  One main problem with second person is that it can sound accusatory. It runs to risk of placing too much responsibility on the shoulders of the reader specifically and presently reading the work. Incorrect example: “If you still disagree nowadays, then you must be ignorant of the facts.” Correct example: “Someone who still disagrees nowadays must be ignorant of the facts.” Sometimes, a writer will need to refer to someone in indefinite terms. In other words, they may need to generally address or speak about a person. This is usually when the temptation to slip into the second person “you” comes into play. An indefinite third person pronoun or noun is appropriate here.  Indefinite third person nouns common to academic writing include: the writer, the reader, individuals, students, a student, an instructor, people, a person, a woman, a man, a child, researchers, scientists, writers, experts. Example: “In spite of the challenges involved, researchers still persist in their claims.” Indefinite third person pronouns include: one, anyone, everyone, someone, no one, another, any, each, either, everybody, neither, nobody, other, anybody, somebody, everything, someone. Incorrect example: "You might be tempted to agree without all the facts." Correct example: “One might be tempted to agree without all the facts.” One mistake that writers often make when writing in third person is accidentally switching into a plural pronoun when the subject should be singular.  This is usually done in an attempt to avoid the gender-specific “he” and “she” pronouns. The mistake here would be to use the plural “they” pronoun in place.  Incorrect example: “The witness wanted to offer anonymous testimony. They' were afraid of getting hurt if their name was spread.”  Correct example: “The witness wanted to offer anonymous testimony. He or she was afraid of getting hurt if his or her name was spread.”

Q: twice a day. Even if you're in a hurry, brushing your teeth will remove bits of food, bacteria, and stains that can cause problems if left to fester. Try brushing once in the morning and once before you go to bed, and spend at least two minutes each time you brush. It will keep you fresh the whole day.  If you are constantly on the go, have a travel toothbrush in you purse or briefcase so you can pop into the bathroom at work. Spend equal time brushing the front, back, and tops of your teeth, especially the molars. Your dentist is not lying when he says this is one of the most overlooked hygiene regiments in America. Regular flossing cleans the parts of your teeth a brush can't reach and stimulates healthy gum growth.  Using a short piece of floss, get in between your teeth and along the gum line, using your fingers to add pressure. Take to your orthodontist about ways to floss if you have braces, such as dental threads. Be sure to clean in between your back teeth too, using the floss around all sides of the molars. Mouthwash does not physically remove plaque and food and is not a substitute for flossing. While going to the dentist every six months is not strictly necessary for healthy adults, children and those with dental issues should talk to their dentists about frequent checkups. Monitor your teeth, note any changes or worrisome pains, and get your teeth professionally cleaned at a minimum of once a year.  Smokers, diabetics, and people with a history of cavities should see the dentist twice a year or more.
A: Brush your teeth Floss at least once a day. Schedule regular visits to the dentist.

Article: Check the center of the cheesecake with the point of an instant-read cooking thermometer near the end of the cooking time. When the cheesecake reaches a temperature of 150 degrees Fahrenheit (65 degrees Celsius), it should be removed from the oven.  A cheesecake will always crack if the internal temperature rises above 160 degrees Fahrenheit (70 degrees Celsius) during the baking process. The thermometer will leave a hole in the center of your cheesecake, so you can skip this step if you want a perfectly smooth surface. Many people consider a hole to be far less distracting than surface cracks, though. Since the thermometer will allow you to measure the doneness on a detailed level, it's a valuable tool in the battle against surface cracking and definitely has its benefits. The cheesecake is done with the outer perimeter is firm but 2 to 3 inches (5 to 7.6 cm) of the center is still wobbly.  Note that while the center should look moist and wiggly, it should not look runny. The center will firm up as the cheesecake cools. If you bake the cheesecake until the center appears dry, you'll end up drying the cheesecake out. This dryness is another factor that can cause surface cracking. After pulling the cheesecake out of the oven, let it cool undisturbed only for a few minutes. After those minutes pass, run a smooth paring knife around the inner sides of the pan, separating the cheesecake from the pan. Since cheesecakes shrink as they cool, this action further prevents the dessert from clinging to the sides of the pan as it shrinks and tearing apart at the center. Allow the cheesecake to cool at room temperature until the cake itself drops down to room temperature.  Do not refrigerate the cheesecake immediately after pulling it out of the oven. The dramatic shift in temperature can cause cracks to form. Place an inverted plate or cookie sheet over the cheesecake as it cools to protect the surface. After the cheesecake drops to room temperature, refrigerate it for another six hours or until it fully solidifies.
Question: What is a summary of what this article is about?
