Problem: Write an article based on this summary: Understand how a polygraph works. Try not to overthink the test beforehand. Take care of your body the night and day before. Complete any forms given to you. Tell the examiner about any conditions or medications you take. Review the questions and take your time understanding them. Find out which test form will be used.

Answer: A polygraph cannot detect a lie, per se, but it does track physiological changes in your body, like your blood pressure, pulse, respiration, and perspiration, thereby detecting physiological conditions that occur when you lie. Once you arrive for the appointment, the equipment and process will be reviewed. It does not hurt to familiarize yourself with the basics on your own, but avoid polygraph horror stories posted on the Internet, since these will only make you more nervous than you need to be. If you spend too much time worrying about the polygraph test before you take it, you run the risk of skewing the test against your favor by finding things to condemn yourself on needlessly. To avoid worrying yourself unnecessarily, do not ask anyone who has taken a polygraph what it was like, do not spend time soul-searching before the test, and do not try to anticipate which questions will be asked. Try to avoid spending too much time reviewing anti-polygraph websites, since these websites often mix fact with hyped-up conspiracies and may cause undue panic. You need to be comfortable during the polygraph in order to provide accurate physiological responses. In order to be comfortable, you need to make sure that you are well-rested and feeling as physically cozy as possible. Follow your usual routine as accurately as possible. Even if your routine includes activities that affect your heart rate, like drinking caffeinated coffee or going for a morning run, you should follow your routine since your body has trained itself to run on those physiological conditions. Try to get seven or eight hours of sleep the night before the test. Make sure that you are not hungry and that you have loose, comfortable clothes on. Depending on the reason for the polygraph, you might have security clearance forms to fill out or forms requiring your authorization. Take your time on these forms. Read through them carefully and sign your name only when ready. If you are currently ill, the examiner may want you to reschedule the test. Certain drugs, like blood pressure medication, can also affect the results, so you should let the examiner know about those, as well. Illness can make you feel uncomfortable, thereby skewing the results. If you take prescription medications, you should continue taking them as prescribed by your doctor before the test. Contrary to popular belief, most anti-depressant medications cannot alter a polygraph and allow you to "beat" it. You should still tell your examiner about these medications, if applicable, since they can produce abnormal results. The polygraph examiner is required to tell you the questions ahead of time. Take all the time you need reviewing them, and feel free to ask the examiner for clarification about uncertain or confusing questions. You must ask for clarification about questions before the test. In most cases, you will not be permitted to do so during the test. In fact, your answers will be limited to "yes" and "no" during the polygraph exam itself, so any discussion you need to have about the test questions must take place before the test itself. The standard polygraph test is the CQT, or "Control Question Test." In some instances, however, you may be given a "Directed Lie Test" (DLT) or "Guilty Knowledge Test" (GKT) instead. With a CQT polygraph, control questions will be mixed in among the relevant questions. A control question is one that nearly everyone will need to reply "yes" to, even though many people will be tempted to reply "no." Such questions include ones like, "Have you ever told a lie to your parents?" or "Have you ever stolen or borrowed something without permission?" With a DLT, you will be asked several questions by the examiner and directly asked to lie about those questions. In doing so, the examiner can gauge your physiological responses to lying by reviewing the questions he or she knew you lied on. For a GKT, you will be asked multiple choice questions about various facts that only you and the examiner would know. Many of these questions will be about the case. Your verbal responses will be compared to your physiological responses.

Problem: Write an article based on this summary: Use the "fade out" method. Decline invitations from the person. Excuse yourself from conversations. Take a more active approach to ending the friendship.

Answer: Gradually seeing the person less often might be happening naturally, or you might need to consciously apply these steps. This is a good way to let someone know you don't want to be friends without verbally explaining it to them. This method is appropriate for casual friends who you don't really know very well. If the person is a new friend, this method is less leaving a friendship than it's simply an acknowledgment that you never really became friends. It might take a longer time to leave a friendship this way. One way that you can start to minimize contact with the person is by declining invitations to do things. This may require you to tell a little white lie now and then to get out of something. For example, if the person asks if you want to go see a movie sometime over the weekend, then you might say something like "That sounds cool, but I already have a ton going on this weekend, so I really can't." You may bump into the person while you are trying to build distance between the two of you, so you will need to know how to deal with those situations. Ignoring the person could lead to hurt feelings and awkwardness, so instead try to give polite excuses for why you can't stay and talk. For example, you could politely say hello to the person and then say something like, "Sorry I can't stay and chat. I am already running late. Maybe some other time!" Try to be as polite and considerate as possible. Even if you do not want to be friends with the person anymore, you never know when you might bump into each other again and keeping things civil will reduce the chance of an awkward run-in. If your attempts to politely and gradually end the friendship do not help, then you can also try telling the person that you don't want to be friends anymore. You may just have to be direct and say something like, "You are a great person, but we are just too different. I wish you all the best, but I think we should stop spending so much time together." Try to avoid the strategy called "ghosting." Ghosting is when you cut off all contact with the person. For example, you would need to ignore the person's texts and emails, stop returning phone calls, and unfriend the person on social media. Ghosting can lead to hurt feelings, anger, and concerns about your well-being, so it is not ideal.

Problem: Write an article based on this summary: Launch the OS X "Terminal. Find the file path of the file you are interested in. Enter the terminal command "touch -mt YYYYMMDDhhmm.ss [file path]" into the Terminal. Enter the command "touch -at YYYYMMDDhhmm.ss [file path]". Enter the command "touch -t YYYYMMDDhhmm.ss [file path]".

Answer:
" Pull down the "Applications" menu, then click on "Utilities", then launch Terminal. Drag and drop the file onto the Terminal window, and Terminal will provide the file path at the command prompt. The file path can then be copied. This will change the modification date. This sends a command to the touch utility (which sets the modification and access times of files) to set the new date and time. NOTE: YYYY means the year, MM the month, DD the day, hh the hour, mm the minute, ss the second of the target time. This will change the access date. This will change the creation date, unfortunately, only if the target time is before the original creation time. If your target time is after the original creation time, see the citation for the solution.
