It’s a little surprising that the land of Sir Isaac Newton does not have its own space agency. An attempt to fill that void came with the announcement in June that the United Kingdom would create a ‘bureaucracy busting’ organization to oversee British civilian space and satellite activities.
What does the author of the passage refer to by the term “void”?

An old axiom says that in order to know where you are going, you first have to know where you are. To
that, add that you should know which way you are facing. Makers of wireless handsets, proving the old
axiom true, have already installed Global Positioning System (GPS) receivers, and are now poised to
flood the market with phones containing tiny electronic compasses that allow the gadget to sense exactly
what direction it’s facing.
What is known about the makers of wireless handsets?

Recently, I was looking for something online, or probably browsing aimlessly, when I happened on a
name I hadn’t thought of since I was a child: Alfred P. Morgan. Someone had uploaded a digitized
version of The Boy Electrician. I was instantly swept back more than half a century to my local library. In
my mind I saw the familiar metal shelving and the blue-gray binding of my favorite book, also written –
and illustrated – by Morgan: The Boys’ First Book of Radio and Electronics.
Which of the following expressions is a synonym for ‘aimlessly’ on the first line of the text?

Soon enough, say some engineers, miniature wireless sensors will be located in spots where it would be
inconvenient, to say the least, to change their batteries – inside your body, within the steel and concrete
of buildings, in the dangerous innards of chemical plants. But today, even the most robust nodes can be
counted on to last only a few years. Ideally, engineers need wireless sensors that can last forever without
external power sources or battery changes. According to research presented in December at the
International Electron Devices Meeting, in Baltimore, that dream is within reach.

The history of technology is full of breakthroughs in one field that wound up working wonders in a
related one. The 300B vacuum tube, introduced by Western Electric in 1937 to amplify telephone
signals, found a far more enduring use as a high-fidelity audio amplifier. The atomic clocks first used
in the 1960’s by the U.S. military to track Sputnik and later to validate Albert Einstein’s relativity
theories are now the basis of Global Positioning System. And of course, the magnetron, invented in
the 1920’s at General Electric and used in radars during World War II, later found itself repurposed as
the basis for the microwave oven.
According to the text, complete the sentence: “The microwave oven…”

Scientists say juggling e-mail, phone calls and other incoming information can change how people think
and behave. They say our ability to focus is being undermined by bursts of information. These play to a
primitive impulse to respond to immediate opportunities and threats. The stimulation provokes excitement
— a dopamine squirt — that researchers say can be addictive. In its absence, people feel bored. The
resulting distractions can have deadly consequences, as when cell phone-wielding drivers and train
engineers cause wrecks. And for millions of people these urges can inflict nicks and cuts on creativity
and deep thought, interrupting work and family life.

Is ‘Facebook’, the social networking website, making us narcissist? A new book argues we’re much more
self-absorbed nowadays, stating that technology is to blame. I tweet, therefore I am. Or is it, I tweet,
therefore I am insufferable? As if adult celebrities that pop out on the red carpets weren’t clue enough,
we now have statistical evidence that we are a lot more in love with ourselves than we used to be. This
social phenomenon has raised fields of research to academic studies nowadays. In the book ‘The
Narcissism Epidemic: Living in the Age of Entitlement’, Jean M. Twenge, a professor of psychology at
San Diego State University, and W. Keith Campbell, a social psychologist at the University of Georgia,
look to the Narcissistic Personality Inventory, which measures self-regard, materialism, and lack of
empathy. They found that the number of college students scoring high on the test has risen by 30 percent
since the early 1980’s.
What has NOT been encouraging people to act the way described in the text?
