In one sentence, describe what the following article is about: Power lines, trees, etc should be removed, lowered and/or lighted. Stabilize with topsoil and grass seeding if necessary.
Summary: Clear entire area. Completely remove roots of trees and shrubs. Fill in low areas. Eliminate any breaks in grade or surface mounds as well as any ditches. Fill in and compact the soil in any animal burrows. Remove any obstructions at the ends of the strip. Grade the strip 6 inches (15.2cm) higher in the middle to improve drainage. Mark airstrip boundaries in such a way as to be visible from the air. Create a tie-down area away from the airstrip.

In any number, the different digits represent different amounts. For instance, in the number 1,872, the "1" represents thousands, the "8" represents hundreds, the "7" represents tens, and the "2" represents ones. When there is a decimal point in a number, the numbers to the right of the point represent fractions of one. The places to the right of the decimal point have names that mirror the names of the whole number decimal places. The first number to the right of the decimal point represents tenths, the second represents hundredths, the third represents thousandths, and so on for ten-thousandths, etc. For example, in the number 2.37589, "2" is the number of ones, "3" is the number of tenths, "7" is the number of hundredths, "5" is the number of thousandths, "8" is the number of ten-thousandths, and "9" is the number of hundred-thousandths. The first step to rounding a decimal is to determine which decimal place you're going to round it to. If you're doing schoolwork, this information is usually given to you often, the problem will say something like, "round the answer to the nearest tenth/hundredth/thousandth." For example, if you are asked to round to the nearest thousandth in the number 12.9889, you would start by finding the thousandths place. Counting from the decimal point, the spaces to the right represent tenths, hundredths, thousandths, and ten-thousandths, so the second "8" (12.9889) is the one you want. Sometimes, instructions will tell you exactly which decimal place to round to (e.g., "round to the third decimal place" means the same thing as "round to the nearest thousandth"). Now, find the decimal place to the right of the place you're rounding to. Based on the number in this place, you'll round either up or down. In our example number (12.9889), you're rounding to the thousandths place (12.9889), so now look at the number to the right of this, which is the final "9" (12.9889). To be clear: if the place you're rounding to is followed by a 5, 6, 7, 8, or 9, round it up. In other words, make that decimal place one value greater and get rid of the digits after it. In the example number (12.9889), since the final 9 is higher than 5, round your thousandths place up. The rounded value becomes 12.989. Note that you drop the digits after the rounded decimal place. On the other hand, if the place you're rounding to is followed by a 4, 3, 2, 1, or 0, round it down. This means to leave the rounded digit as it is and get rid of the digits after it. You wouldn't round 12.9889 down because the final 9 isn't 4 or lower. However, if you were working with the number 12.9884, you could round it down to 12.988. Does this process seem familiar? If so, it's because this is basically how you round whole numbers the decimal point doesn't change things. One common rounding task is to round a number to the nearest whole number (sometimes, this will be explained as "rounding the number to the ones place"). In this case, use the same rounding technique as before. In other words, start at the ones place, then look at the number to the right. If this number is 5 or greater, round up. If it is 4 or lower, round down. The decimal point in the middle doesn't change anything. For example, if you needed to round the example number from earlier (12.9889) to the nearest whole number, you'd start by looking at the ones place: 12.9889. Since the "9" to the right is greater than 5, you would round up to 13. Since you've gotten a whole number answer, you don't need the decimal point any more. The directions for rounding above will work well in general. However, when you've been given special directions for rounding decimal places, make sure to follow them before you use the normal rounding rules. For example, if you receive the instructions "Round 4.59 down to the nearest tenth", you'd round the 5 in the tenths place down even though the 9 to the right means you'd normally round it up. This would give you 4.5. Similarly, if you are told to "round 180.1 up to the nearest whole number," you'd round to 181 even though you'd normally round down.

One-sentence summary -- Understand the idea of decimal places. Find the decimal place you need to round to. Look at the number in the space to the right. If this number is greater than or equal to five, round up. If this number is less than five, round down. Use the same technique to round to a whole number. Look out for special instructions.

Problem: Article: To stretch out your abs, complete the "Superman" pose. Lie on your stomach and reach your arms forward and your legs backward while lifting them slightly off the ground. You can also try child's pose to stretch out. This consists of sitting on your heels, bringing your stomach to your thighs, and stretching your arms out in front of you. Perform the same number of sequences each time until you feel ready to add additional sequences. To start feeling results, aim to do at least three sequences three days a week. For faster results, increase the number of times per week you do this exercise. Traditional Pilates involves working through a sequence of moves, and the goal is to perform each move one time correctly, concisely, and with control. One great way to improve your form and to learn other complementary exercises is to attend a class or take lessons. With time and practice, you can learn how to perform the corkscrew properly using the method of Joseph Pilates. Concentrate on perfecting your technique rather than doing numerous repetitions.
Summary:
Stretch out upon completion. Repeat exercise three times a week. Consider taking Pilates classes.
