Question: Article: Treat with Respect The speed with which Man is changing the face of Earth has outstripped all the mighty processes of nature put together. In his haste to supply himself with increasing quantities of Earth's treasures he risks destroying one he greatly needs, his natural surroundings. Some countries set aside unspoiled areas of natural beauty. prefix = st1 /Canadahas the largest system of national parks in the world, 29 in all covering about 13 million hectares, preserving the different landscapes and the plant and animal life. Other countries are restoring areas which have been reduced to waste land by mining. At Broken Hill in Australiadrifting sand from rock crushing turned the area into a desert swept by sand storms. This is now being irrigated, fertilized and planted with grass and trees. In Great Britain quarries and gravel pits are being filled in or made into lakes, industrial wasteland is being turned into playing fields and waste tips into sloping green hills. However Man tries to look after Earth, the fact is that he is using up at a great rate resources, especially fuel resources, which have taken millions of years to accumulate and which he cannot renew. Yet every day the Earth receives a huge supply of energy from the Sun. Man has made several experiments in using solar energy to heat furnaces , cookers, and water-distillers. In space technology, e.g. on satellites, solar cells convert sunlight into electricity. Houses and offices have been designed which are centrally heated by water or air heated by the sunlight. When Man can trap and store this energy, so that he can use it exactly as he needs it, he will have not only an endless supply, but a clean and safe one.
Answer: Energy from the Sun.

Answer: According to this selected passage, which energy is considered to be endless, clean and safe?

Question: Article: Security--for the information on your smart phone, as well as for the phone itself--is a hot topic these days.The truth is that you're packing a lot of sensitive information on your phone, and you should keep it safe. When it comes to physical security, iPhone users would do well to download Find My iPhone, a free app from Apple that allows you to visit a website and see your (lost, stolen or misplaced) phone on the map.You can then sound an alarm, send a message that will pop up on its screen, lock the phone or erase all your data. Android does not have an exact equivalent , but there are plenty of alternatives. A free app called Lookout offers the findmyphone feature.The paid version allows you to wipe the data from your phone remotely. Then there is your coffee shop's WiFi network.Anyone with minimal technical expert skill can snoop on people using shared wireless networks, harvesting passwords and other personal data. Lookout will caution you when you've logged on to an insecure network, but cannot protect you once you're there. In order to protect yourself on such networks, you can use a virtual private network, or VPN. This turns all your activity into nonsense to anyone trying to read along with you from across Starbucks. It also keeps websites from tracking you and, if you're travelling, allows you to get access to sites that may be blocked in other countries. If you have an iPhone, the simplest VPN app is probably Hotspot Shield, whose distinguishing feature is said to be that it automatically kicks in each time you start browsing , as opposed to other VPN apps that require you to start them up manually .This matters, because even if you decide you want a VPN app, you want to spend approximately zero time thinking about it. For the most part, _ was true of Hotspot Shield, though occasionally it took a while to connect or temporarily lost connection without warning. I found myself having to turn the app on and off sometimes, which involved setting my phone constantly. If even reading about the settings on your phone drive you crazy, then it is probably best to stay away from a VPN app. But if you're the type who can't resist checking your bank balance from your corner bar, the hassle may be preferable to the risk.
Answer: Find My iPhone.

Answer: Which of the following can warn you against the insecure network?
