Q: Read the following article and select the best answer. Article: Your brain isn't a muscle, but you can treat it like one Many people focus on physical fitness, but few know that brain fitness is also something you can work on. In fact, you can exercise your brain as often as you do to your arms or legs-and the results can be positive and empowering. To improve your brain, you can't simply repeat the same exercises over and over. Just as lifting a two-pound weight will stop challenging you, so will repetitive exercises such as crosswords or Sudoku. Once you master easy exercises, you must move on to harder ones in order to push your brain-like your muscles-to a new level. The science behind brain training Scientists once believed that your mental abilities were fixed in adulthood. Since studies have shown just the opposite, millions of people around the world have adopted the new practice of brain training. The most popular of these brain training products is made by the San Francisco-based Lumosity. Lumosity's scientists with an experienced team of game designers have developed a fun,effective online brain training program that measures, tracks, and adapts to your progress, so you'll always be challenged. Promising studies on the effects of brain training In a 2013 Stanford study, a treatment group of 21 breast cancer survivors used 12 weeks of Lumosity training to work on processing speed, mental flexibility, and working memory tasks. On average, those who trained improved on tests of these abilities, compared to a group that did not train with Lumosity. There is even some evidence suggesting that Lumosity may be beneficial to normal, healthy adults. In a 2011 study by Lumosity and San Francisco State University researchers. 13 people who trained over 5 weeks improved working memory scores by 10%and attention scores by 20%. Brain training is designed to meet real-life needs The design of brain train ing is targeted at real-life benefits instead of improving game scores. Better attention, for example, can mean greater focus in the classroom or at an important business... Question: Which skill may brain training not improve? - Better attention. - Better writing skills. - A better memory. - Higher processing speed.
A: A better memory.

Read the following article and select the best answer. Article: At 57 you would think I know what my future looks like. But I don't. I'm still searching for it. Our friends are becoming grandparents. My kids are still in college, so this makes me feel younger than I am. I felt the same way in my 40s when my friends' kids were entering high school and I was attending Christmas shows at the elementary school. "What do you mean you've never heard of Barney or the Rugrats?" I'd ask. At the age of 57, I find myself trying to find meaning at a time when some might think my best days are behind me. Each morning I wake with the intention of finding the sunshine in the day ahead. I am working temporary accounting jobs because that is the job I fell into many years ago, but I spend most of my time writing. When asked what I do for work, I find myself answering, I am a writer. I've published two novels, I blog, and I write pieces here on the Huffington Post, so yes, at 57 I can call myself a writer. At this point in my life I realize Paul Bowles was correct when he said "security is a false God". What I am searching for at 57 are not possessions or money in the bank, for all those things can be lost in an instant. Job losses, illness, the loss of a loved one, all these things can and will rock that false sense of security. At 57 I live with the choices and mistakes I have made, along with the curveballs that were thrown in my way. I accept the fact that there will always be more questions than answers. As at any age, the only true choice I have is how I deal with life's ups and downs but at 57 I have come to accept this. Time is my most precious commodity and I intend to make the most of it. Question: What is the author's attitude towards life? - Cautious. - Worried. - Enthusiastic. - Passive.
(A).
Enthusiastic.
