PROBLEM: Article: Long after the 1998 World Cup was won, disappointed fans were still cursing the disputed refereeing decisions that denied victory to their team. A researcher was appointed to study the performance of some top referees. The researcher organized an experimental tournament involving four youth teams. Each match lasted an hour, divided into three periods of 20 minutes during which different referees were in charge. Observers noted down the referees' errors, of which there were 61 over the tournament. Converted to a standard match of 90 minutes, each referee made almost 23 mistakes, a remarkably high number. The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were more likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum   distance is about 20 meters. There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second. If FIFA, football's international ruling body, wants to improve the standard of refereeing at the next World Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues. He also says that FIFA's insistence that referees should retire at age 45 may be misguided. If keeping up with the action is not so important, their physical condition is less critical. 
 Answer: analyse the causes of errors made by football referees

SOLUTION: The experiment conducted by the researcher was meant to   _  .

PROBLEM: Article: Every year, millions of Americans see their personal information leak into the wrong hands. Maybe there's spyware on the their computer, or a service they use suffered a security reach, leaving customers at the risk of exposure. Or perhaps their password is easy to guess. Don't fear: You can easily set up proper defenses. Here's how. * Clean Your Computer and Smartphone Before you put new security measures into place, make sure your devices are as spotless as possible. This means installing a good antivirus program and taking the time to clear out any spy -- or malware that may have already infected your system. These days, it's also worth it to make sure your phone is safe from viruses. Iphones are less likely to be targeted by spyware, but Android users should download the Lookout app to scan their devices and ensure everything is as it should be. * Secure Your WiFi. It's fairly easy for potential criminals to gain access to your information if they're able to share your connection -- that's why you want to be careful when using public WiFi. Even though you put security measures into place a couple of years ago, it's a good idea to refresh your settings. * Use passwords What you've heard is true: Passwords should use a variety of special characters, numerals, letters, and cases when possible. * Check the shopping security Take care when shopping online. Always check the security symbols when using an online site for shopping. If the lock icon encryption    is not there, do not give out credit details. Also, check that the site is legal -- never go to a site from a random email and start shopping online. Keep a separate credit card just for online shopping. This will make it easier to cancel if something bad does happen and your other credit card for "in real life" can still be used uninfluenced. Don't store information on any store's website. It may be convenient but it's also a possible loss to you if the site is hacked.
