Summarize the following:
Most modern tillers come in one of two varieties: "front-line" (driven by the front wheels) and "rear-line" (driven by the rear wheels). Both will work for gardens and small fields, but if you have the choice, pick the type that's most appropriate. See below: Front-line tillers are typically easier to use and better for smaller gardening situations. They handle like a power lawnmower and, with a little care, can be used in tight spaces without damaging plants or property on either side. Rear-line tillers are a little harder to use but are better for bigger plowing jobs. They are bulkier and don't allow for as precise of turns, so they should be used away from plants and property you want to protect. Almost all mechanical tillers allow you to adjust these settings with controls on the unit. As a general rule, harder, compacted soils require slower, shallower plowing. Tilling too deep or too fast in this soil can overwork the motor. For established beds, you can use deeper, faster tilling. Position the tiller in the corner of your field where you plan on starting. Start the tiller with the starting mechanism. This can vary from unit to unit but is often similar to the type of mechanism you might expect on a lawn mower. Use the tiller's controls to slowly work your way down the plot in a straight line, turning around and doubling back at the end. Some tillers have a safety switch that prevents starting. If you can't get the tiller started, check for one of these. Be prepared to go over your work a second time with the tiller. Any clods of dirt should be broken into roughly dime-sized pieces or smaller. When you're finished, your plot should be tilled into a series of loose furrows so that water can drain to the edges.

summary: Pick an appropriate tiller for the job. Pick an appropriate tilling depth and speed. Till in straight rows. Re-till if needed to break down the soil.

Summarize the following:
Imagine that a 120 pound woman consumed four 1.5 ounce drinks of an 80 proof liqueur over a five-hour period. Four 1.5 ounce drinks of an 80 proof liqueur is equivalent to four standard drinks in the United States. Multiply the number of standard drinks in this example (4) by 14 (the number of grams of alcohol in a standard drink in the United States) to find the alcohol dose, 56 grams of alcohol. 120 pounds is equivalent to 54480 grams (120 pounds x 454 grams per pound). Multiplying this by the gender constant (in this example, 0.55) = 29964 ). In this example, this equals approximately 0.0018689093579 (56 / 29964). For a less exact calculation, you can round this number to 0.00186. In this example, this gives the number 0.186 (0.00186 x 100). This number reflects the approximate BAC as a percentage, before accounting for elapsed time. In this example, you should first multiply the number of elapsed time in hours (5) by 0.015 = 0.075. Then, subtract this number from the approximate BAC as a percentage: 0.186 0.075 = 0.111. This means that the approximate BAC in this example at the end of the five hour period is 0.111.

summary: Understand the example. Count the number of drinks. Find the alcohol dose. Multiply the body weight in grams and multiply it by the gender constant. Divide the alcohol consumed in grams by (body weight in grams x gender constant. Multiply the raw number by 100. Account for elapsed time.

You need a long strand so that it's easy to grip. Additionally, you'll use a fresh section of floss when you switch teeth, so it's helpful to start with a long piece of floss. If the piece of floss you pull off is too short, it's no big deal. You can just pull off a new piece of floss when you need it. Start with 1 hand, then do the other. Make several loose wraps around each of your middle fingers until the floss pulls taut. However, don't wrap the floss so tightly that it digs into your skin or cuts off your circulation. The wrap should feel loose and comfortable around your fingers. If the floss feels like it's wrapped too tightly, unwind it and try again. Use the thumb and forefinger on each hand to hold the floss, and create a space of about 1 to 3in (2.5 to 7.6cm) between your hands. This is the part of the floss you'll be using to floss your teeth. As you floss, you'll move your fingers along the floss to isolate a fresh section for flossing. Work with sections that feel comfortable for you. If a larger section feels right, then it's okay to leave more space between your hands.
summary: Break off about 18 to 24in (46 to 61cm) of dental floss. Wrap the ends of the piece of floss around your middle fingers. Hold a 1 to 3in (2.5 to 7.6cm) section of floss between your thumbs and forefingers.
