Problem: Article: You shouldn't feel pressured to bulk up a survey with questions. The more questions you ask, the less likely it is that a customer will finish the survey. As a rule of thumb, ask no more than 10 questions, and preferably fewer. For example, you might only want to know someone's overall experience. In that situation, you can simply ask, “Please rate your overall experience on a scale of 1 to 10, with 1 being the worst and 10 the best.” You can glean more information from a customer if you ask questions that can't be answered with a “yes” or “no.” For example, don't ask, “Were you happy with your experience?” Instead, you can ask, “What would you change about our business to improve it?” The second question can't be answered with a "yes" or "no." If you use open-ended questions, you must decide where to put them. Some experts suggest putting them at the front of the survey so they are answered first. However, recent research suggests that open-ended questions can make a customer more positive than they normally would be when filling out the rest of the survey. Accordingly, you might want to put them at the end. You'll only waste people's time if you ask a bunch of irrelevant questions. Instead, you can segment your customer base. For example, you don't need to ask recent customers their opinions about your customer support, since they probably haven't used support yet.  Segment your customer base any way you want. For example, if you offer many different services, you can segment them based on the service they use. Alternately, you can segment customers based on how long they have done business with you. One reason so few people offer feedback is that they don't really think you care. However, you should assure customers that you will respond promptly if they have a problem. Write, “We will respond ASAP to any concerns.” Remember to follow through. You'll harm your business' reputation if you promise to respond promptly but don't.
Summary: Ask only questions you want answers to. Consider open-ended questions. Tailor questions to your customers. Promise to respond promptly.

INPUT ARTICLE: Article: The best way to do this is by turning off the electricity supplied to the circuit on which you will be working at the junction box (also called a fuse box) for your home. Switch the breaker of your fuse-box so the fuse for the circuit supplying electricity to your fixture reads "Off." It's always a good idea to double-check the flow of electricity by checking the light itself before moving forward with this project. Flick the light on, and if the circuit has been disabled, the light should stay off. If the light you are wiring is in the ceiling, you should clean any cobwebs and dust before attempting to install your new fixture. The same is true for lights or switches in walls; a clean work area will improve your ease of installation. If you are using a ladder to reach your light fixture, or are in a less than ideal position, be sure the ground is also clear of debris or anything else that might affect your balance or safety. There is usually, but not always, a decorative globe, shield, or some kind of external feature covering your existing light fixture. This could also be something more involved, like ceiling fan blades. There will be a mounting bracket holding your old fixture in place. You will need to unscrew this from mounting bracket, usually with Phillips-head screwdriver, and then pull it from the bracket. Be sure you support the old fixture with your hand as you unscrew it from the mount. If you do not support the fixture, it could fall to the floor once you loosen the screws holding it in. Allow the unscrewed fixture you are supporting with your hand to descend a few inches below its mount. You will likely see three wires attached to your fixture: a hot wire, grounding wire, and neutral wire. You will need to use your free hand to uncouple these wires, twisting the wiring cap to free the wires from each other.  Hot wires are those that run electricity to your fixtures and grounding wires are intended to offer surge electricity a neutral point, like the earth, into which it can dissipate.  In some cases, a grounding wire might be attached to the mounting bracket itself, rather than a house wire. This is fairly common in new light fixtures. You should see plastic caps, called wiring caps (also called a wire nut), with two wires running into each cap. One wire will come from the light, the other from the main electrical circuit of your house. Disengage the wires by twisting the wiring cap until it comes free. Once you have released the light from its wiring, you can set the existing light fixture aside.

SUMMARY: Cut power to your circuit. Clean the old fixture and installation area. Remove the old fixture covering. Unmount the fixture. Lower the fixture. Disengage your light from its wires.

In one sentence, describe what the following article is about: 102 is 100. 103 is 1000. The powers 2 and 3 are the base-10 logarithms of 100 and 1000. In general, ab = c can be rewritten as logac = b. So, saying "ten to the power of two is 100" is equivalent to saying "the base-ten log of 100 is two." Each logarithmic table is only usable with a certain base (a in the equation above). By far the most common type of log table uses base-10 logs, also called the common logarithm.  Multiply two numbers by adding their powers. For example: 102 * 103 = 105, or 100 * 1000 = 100,000. The natural log, represented by "ln", is the base-e log, where e is the constant 2.718. This is a useful number in many areas of math and physics. You can use natural log tables in the same way that you use common, or base-10, log tables. Let's say you want to find the base-10 log of 15 on a common log table. 15 lies between 10 (101) and 100 (102), so its logarithm will lie between 1 and 2, or be 1.something. 150 lies between 100 (102) and 1000 (103), so its logarithm will lie between 2 and 3, or be 2.something. The .something is called the mantissa; this is what you will find in the log table. What comes before the decimal point (1 in the first example, 2 in the second) is the characteristic. This column will show the first two or, for some large log tables, three digits of the number whose logarithm you're looking up. If you're looking up the log of 15.27 in a normal log table, go to the row marked 15. If you're looking up the log of 2.57, go to the row marked 25.  Sometimes the numbers in this row will have a decimal point, so you'll look up 2.5 rather than 25. You can ignore this decimal point, as it won't affect your answer. Also ignore any decimal points in the number whose logarithm you're looking up, as the mantissa for the log of 1.527 is no different from that of the log of 152.7. This column will be the one marked with the next digit of the number whose logarithm you're looking up. For example, if you want to find the log of 15.27, your finger will be on the row marked 15. Slide your finger along that row to the right to find column 2. You will be pointing at the number 1818. Write this down. For 15.27, this number is 7. Your finger is currently on row 15 and column 2. Slide it over to row 15 and mean differences column 7. You will be pointing at the number 20. Write this down. For 15.27, you will get 1838. This is the mantissa of the logarithm of 15.27. Since 15 is between 10 and 100 (101 and 102), the log of 15 must be between 1 and 2, so 1.something, so the characteristic is 1. Combine the characteristic with the mantissa to get your final answer. Find that the log of 15.27 is 1.1838.
Summary:
Understand what a logarithm is. Identify the characteristic of the number whose log you want to find. Slide your finger down to the appropriate row on the table using the leftmost column. On the appropriate row, slide your finger over to the appropriate column. If your log table has a mean difference table, slide your finger over to the column in that table marked with the next digit of the number you're looking up. Add the numbers found in the two preceding steps together. Add the characteristic.
