Article: On May 18,1969,NASA astronauts Thomas Stafford,John Young,and Eugene Cernan boarded the Apollo 10 lunar module --the fourth manned mission in the US Apollo Space program and only the second after Apollo 8 to circle the moon.Its mission was to circle the moon and thoroughly test the components and procedures to pave the way for the first lunar landing. The mission went perfectly without incident--at least that's what every one believed. However, that view has changed since February 22, after NASA released a digital recording of strange music heard by the space travelers.Then as they were re-entering the zone where they could communicate with ground control.One of the astronauts asked if they should report it.In response, Stafford expressed his doubts if anyone would even believe them.But they needn't have worried. When NASA experts listened to the recordings,they thought the strange sounds were radio interference. Michael Collins--the Apollo 11 pilot--said that the only reason why he was not shocked upon hearing them was that he had been forewarned by NASA officials.Collins also said that the music stopped as soon as the lunar module landed on the moon. So why did it take NASA over 40 years to release the digital recording of the awful music only after it was featured in a recent television series NASA's Unexplained Files? The US Space Agency says they have not been hiding them.In the press release that accompanies the release of the recording,NASA officials state,"The Apollo 10 audio clips were uploaded in 2012, but the mission's sound recordings have been available at the National Archives for anyone that wanted to hear them since the early 1970s." Eugene Cernan, Apollo 10's pilot who heard the sounds first,also released a statement saying,"I don't remember that incident excited me enough to take it seriously.It was probably just radio interference.Had we thought it was something other than that,we would have briefed everyone after the flight. We never gave it another thought." While most people are ready to...

Read the following article and select the best answer. Article: Researchers recently found that hackers took control of 300,000 home routers . Once your home router has been controlled, hackers could redirect your network to malicious websites controlled by hi-tech thieves who could then steal your online back details and other sensitive data. However, there are some simple steps you can take to protect your router. Say no to 12345 passwords First, never leave your router open without a password and make sure you change both your Wi-Fi and router login password from the default one it comes with. If you use the default password , this could give someone access to the router setup, which could allow them to change your router settings, including viewing any security keys. Don't broadcast it Make sure you don't show up in other people's wireless network scans. Know your network name so you can easily enter it into any devices you want to access that network. Other people do not need to know your network name. To prevent outsiders from seeing your network's name and attempting to join your wireless network, turn off broadcasting in your router's settings. Invite only please One way you can ensure no one else joins your network without your permission is to enable your router to only allow certain devices to connect, and ban all others. To do that you can filter by media access control (MAC) addresses. Turn it off This is a simple piece of advice that can go a very long way in keeping you safe. Simply turn off your router when you're not using your network. If you're at work all day and no one's home, why keep it running? Build a firewall The firewall built into your router prevents hackers on the internet from getting access to your PC so it's always worth enabling it to help add an extra layer of security. However, it does nothing to stop people in range of your Wi-Fi signal from getting onto your network - and as said, a router in the wrong place means your Wi-Fi signal could reach pretty far. For further protection, you should run software firewalls on the individual PCs... Question: If you use the default password, _ . - your home router will be linked to some bad websites. - you will find it's very convenient to surf the Internet - your home router will be changed for new settings. - you will fail to use your own login password

Ques: Read the following article and select the best answer. Article: How many times do you have to fail at something in order to succeed? Did you know that Thomas Edison failed 10,000 times while trying to invent the light bulb? He certainly had a "learn and do" attitude! He was able to turn each failed experiment into a successful way to invent the light bulb. So what can we learn from this? You can adopt the "fail forward" strategy too. In reality, none of us are failures. It's true that we will experience times of defeat, problems, and disasters, but remember, each one of us is meant to succeed in life. However, we must choose our fate. Henry David Thoreau said, "Men are born to succeed, not to fail." We can never be forced into having a happy and successful life. Whether or not you experience success or failure is completely controlled by what you think and do. You are the only one who can choose the thoughts that will keep you from achieving the abundant life and joy that you are meant to have. No matter how difficult things may seem, say to yourself, "I choose to be a happy and successful person." Why do some people get what they want and others fail? I believe that getting what you desire in life takes planning, and it doesn't just happen by luck. So how do we plan for success? It has been proven that successful people do things more differently than unsuccessful people. They recognize the patterns of success and follow them; one of those patterns is planning. They plan what they think and do, which sets them apart. They know exactly what they desire, have an intelligent plan for getting it, and then work their plan. They know what success will cost them in terms of time, energy, and results, and they devote the right resources toward making their plans happen. Question: The writer refers to Thomas Edison to _ . - introduce his invention - put forward the topic of the text - praise the inventor - show the way to success
Ans: put forward the topic of the text
