Question: Read the following article and answer the question. Article: In fall 2006,the National Basketball Association (NBA)started using basketballs made with synthetic ,or man-made ,material instead of leather .They made the change be- cause they wanted every basketball they use to feel and bounce the same.Not all leather balls are exactly alike in weight or how they bounce,but the synthetic balls are. However,some players complained right away that the new balls bounced differently and were actually harder to control than the leather ones. Physics helped answer questions about why the new balls felt different.For example,the scientists studied friction ,which in this case affects the ability of a player to hold onto a ball."The greater the friction,the better it will stick to his hand,"explains a scientist. Tests on both wet and dry balls showed that while the synthetic ball was easier to hold onto when dry,it had less friction and became much harder to hold onto when wet.That's because _ stays on the surface of the synthetic balls but gets taken into the leather balls. The scientists also tested bounce and found that the logo printed on the new balls made their surface uneven and caused them to bounce a little strangely com- pared with the leather balls. In January,the NBA went back to using the leather balls.They aren't perfect,but for now,that's just the way the ball bounces. Question: It can be inferred from the text that _ . Answer:
OPTIONS:
- a synthetic ball takes in water faster than a leather ball
- a leather ball is more difficult to make than a synthetic one
- a synthetic ball is more expensive than a leather ball
- a leather ball may increase its weight during a game
Answer: a leather ball may increase its weight during a game

Question: Read the following article and answer the question. Article: As a teacher, my daily life includes driving to a new school so I'm usually unable to anticipate the day's events, good or bad! One day, I was teaching in a very difficult classroom. I was managing behavior all morning and by lunch time, I knew I needed coffee to even consider surviving the afternoon. So on my lunch break, I drove to a coffee shop nearby to get a cup of coffee. While returning to the car I realized I had locked my keys and my phone inside! I had about 15 minutes to get back to the school which was a good 4- or 5- minute drive away. I considered rushing back, but it being winter, I thought a fall on ice would only make the situation much worse. So I ran into a McDonald's and asked the man at the counter who happened to be the manager to please call me a taxi. I explained my situation to him, and I could tell by the look in his eyes, that he took pity. He hurried to the back to use the phone while I walked in the restaurant. I had less than 10 minutes to get back to my school at this point. The manager returned only to tell me that the taxi company had put him on hold and then the line got disconnected, and that he was now on hold again, but had not yet been able to ask for the taxi yet. Without a thought, he caught his coat and offered to drive me to the school. Immediately I followed him into his car and made it back into my classroom with 2 minutes left before the bell! While arriving at the school, I thanked this man endlessly. His calm behavior and kind nature made me think he was probably a wonderful manager to work for, and also a wonderful human being to have on his earth. This experience makes me realize that out of every hopeless situation, there is the chance for acts of kindness to happen, which can create an unimaginable impression to those who receive them. Question: The writer has probably stayed in the McDonald's for about _ . Answer:
OPTIONS:
- 15 minutes
