Problem: Write an article based on this summary: Break down the letter into short, but specific, paragraphs. Target the recommendation. Familiarize yourself with the position. Inform yourself about the person you are recommending. Get feedback.

Answer: Don't ramble, but do flesh out your key points. Try to keep it at one page, covering the various aspects of their recommendation in brief, specific detail.   Introduction Your qualifications, how you know the candidate, general recommendation.   Professional Success Why they will be effective, productive workers. Examples of successes.   Personal Testimony Why they will be a great addition to work and office culture.   Closing. Reaffirm your willingness to recommend them, offer contact information. Is it for an academic post, a job, a volunteer position, a background check, or a personal reference? Write your letter so that it is focused on this purpose. For example, if the letter is part of a job application package, it should focus on the professional qualifications and conduct of the candidate. Get a copy of the job description, if you can, and talk to the person you will recommend. If you know the intended recipient of the letter, ask them about the position as well. The more you know about the position, the better you will be able to tailor your letter to suit the needs of both parties. Spend some time talking to them about their goals and the position they are applying for. Gather together their current resume, any memos or notes you may have on them, and any other information that will help you as you write the letter. The best recommendations are thorough and specific, and having all the information at hand will make the process much easier. If you're not sure of your letter-writing skills, or if your letter will carry a great deal of weight for the candidate's application, ask for feedback from a trusted colleague who may also know the candidate. If you are putting your reputation on the line for this person, you want to put your best foot forward with this letter.


Problem: Write an article based on this summary: Observe the types and movement of fronts. Analyze a Cold front. Analyze a Warm front. Study an Occluded front. Analyze a Stationary front.

Answer: These mark the boundary between warmer air on one side and colder air on the other. If you are close to a front and you know the front is moving towards you, you can expect a change in weather (e.g. cloud formation, precipitation, thunderstorms, and wind) when the front boundary passes over you. Mountains and large bodies of water can distort its path. On a weather map, you will notice some lines that have semi-circles or triangles on either side, or both. These indicate the boundaries for various types of fronts. With these weather patterns, rainfall can be torrential and wind speeds can be high. Blue lines with triangles on one side represents cold fronts on weather maps. The direction the triangles point is the direction in which the cold front is moving. These often bring a gradual increase in rainfall as the front approaches, followed by prompt clearing and warming after the front passes. If the warm air mass is unstable, the weather might be characterized by prolonged thunderstorms. A red line with semi-circles on one side represents warm fronts. The side the semi-circles are on represent the direction in which the warm front is heading. These are formed when a cold front overtakes a warm front. They are associated with various weather events (possibly thunderstorms) depending on whether it is a warm or cold occlusion. The passing of an occluded front usually brings drier air (lowered dew point). A purple line with semi-circles and triangles both on the same side represents occluded fronts. Whichever side they're on is the direction the occluded front is going. These indicate a non-moving boundary between two different air masses. These fronts have long continuous rainy periods that linger for extended periods in one area and move in waves. A semi-circle bordering one side and triangles along the opposite side represents that the front is not moving in any direction.


Problem: Write an article based on this summary: Consider chain-drive openers as a cost-effective option. Consider screw-drive openers for a well-rounded option. Consider belt-drive openers for quiet operation. Consider direct-drive and jackshaft openers for quiet and highly dependable options.

Answer: Chain drives are some of the most popular and durable openers on the market. These drives use a metal chain on a sprocket to lift and lower doors. Chain openers also tend to be some of the most affordable options; however, the affordability and strength of a chain drive come at the expense of noise.  Chain drives are ideal for the heaviest garage door types, including oversized doors, one-piece wood doors, and wind-rated or heavily insulated doors. If you have a detached garage or a garage that is at the opposite end of the house from the bedrooms, then the noise will be less of an issue.  Many upgraded chain-drive models can come with chain separators to help stop the chain from hitting against the track, which cuts down on the noise of a chain drive. Screw drives use a long metal rod threaded like a screw to lift and close garage doors. Due to having relatively few moving parts, a screw drive tends to be quite reliable as well.  If noise is your biggest consideration, screw-drive openers tend to be middle of the pack. They’re not nearly as quiet as belt or direct drives, but they are most typically quieter than chain drives.  Screw drives also require a bit more maintenance than most of the other types. Despite having fewer moving parts, the threaded metal rod meshes against a drive section with plastic teeth to catch the threading. Without the proper lubrication on this drive, the rod can wear on the teeth and eventually strip them, so you must grease the works fairly regularly—approximately every few months.  The type of garage door you have should also be taken into consideration. For heavy wood one-piece doors, the extra weight and strain can wear the teeth in the inner works of the drive down pretty quickly. This makes screw drives most effective with single-car garage doors or steel doors since the thinner materials cut down on weight.  Screw-drive openers also offer some of the faster speeds available. Newer models can open at 10” to 12” per second as opposed to the more standard 6” to 8” per second of most other drive types. Belt-drive openers use a rubber or rubber-like belt on a cog to open and close doors. Since the opener doesn’t have the loud, banging metal parts, it’s one of the quietest options available.  Consider your particular garage door. If your door makes a lot of noise on its track, then the lower volume of the belt opener may be moot.  Pay special attention to the current of belt-drive openers. Alternating current belt openers start and stop at full power, which can cause the door to jerk into movement and lead to noise despite the relative quiet of the drive.  Direct current belt drives offer soft starts and stops that reduce noise even further, as well as reducing wear and tear. Though less common than the other models, these alternatives are gaining in popularity, and both offer additional options for quiet door openers.  Jackshaft openers attach directly to the front wall of the garage, meaning no overhead parts. These models use cables attached directly to the garage door along with pulleys and a rolling torsion bar to lift and lower the door. Many models of this computerized system even include an automatic deadbolt that locks when the door closes for added safety. Due to the compact nature and computerization, jackshaft openers are some of the most expensive models available, and the cable system also means that they only work on sectioned garage doors.  Direct-drive openers still have an overhead rail with a chain, but the actual motor moves along the track with the door connected to the motor via a J-arm. Since the motor moves instead of the chain, these models are also extremely quiet, and since the only real moving part is the motor, they tend to come with extremely good—maybe even lifetime—warranties. They are still on the pricey side, however—comparable to a belt drive opener.


Problem: Write an article based on this summary: Do a deep cleaning once per month. Unplug the machine. Mix a solution of equal parts vinegar and water.

Answer:
Hard water deposits gradually build up in your coffee maker. Yeast, mold and bacteria also tend to accumulate in coffee makers. Once per month, you will need to decalcify minerals and remove grime with water and vinegar. Let the machine cool off for a few minutes. Then, get your cleaning supplies together, such as your sponge, vinegar and dish soap. To get the hard water out of your coffee maker, you will need to mix a solution of equal parts vinegar and water. If your carafe has measuring indicators, you can use it to mix the solution. Then, pour the solution into the reservoir. You could also use a measuring cup to mix the vinegar and water solution.
