Read the following context and answer the question. Context: Happened to me while visiting Chicago a few weeks ago. A young couple with a baby in a pram boarded a crowded bus. The bus driver would not pull out of the stop until the pram was secured in the wheelchair chocks, however an elderly women wouldn't give up her seat (seat needed to be folded up in order to make room for the pram in the wheelchair holding apparatus). We sat there for about 45 minutes while the driver, the mother and the elderly lady argued. At the end, my wife and I offered our seats (more like a commanding, cajoling, what-she-wanted-to hear, kind of discourse), and the lady moved into our seats. The young couple locked down their pram, and the bus took off. Meg and I stood for the rest of the trip. She was really annoyed over having to move, and there was some baggage attached to her situationI hate to have to mention the racial aspects here but it's an important aspect of the story. Most of the passengers were younger white folks (bus was heading through a neighborhood where re-gentrification had taken place). The elderly woman was at least 75 years and the only black person in the front of the crowded bus. She was sitting in a designated seat reserved for elderly or handicapped, and obviously she had earned her status to claim that seat. Unfortunately, it was also the one seat that needed to be vacated if the wheelchair equipment got used. As the bus rode on, her anger simmered. She asked me what I (middle-aged white guy) would do in a spot like that. All I could answer was to offer it up to God. Hot day, no air conditioning on the bus, people just want to get to their destinations. Question: Meg probably believes what of her husband? Answer:

OPTIONS:
- not enough information
- That he is not racist.
- That he is a racist.
- That he is racially biased.

Answer: That he is not racist.

Problem: OPTIONS:
- The caregivers
- The author
- The elderly people
- not enough information
Q: Read the following context and answer the question. Context: Have you ever wondered whether it's worth your while to encourage an older person to start exercising? In 2014, the top-notch journal JAMA published the results of a fantastic research project: a study in which 1635 sedentary older adults (aged 70-89) were assigned to get either a structured exercise program, or a program of "successful aging" health education. The researchers called it the Lifestyle Interventions and Independence for Elders (LIFE) study. (You can read the full study here.) During the LIFE study, the two groups were followed for a little over 2.5 years. And by the end of the study, guess which group of volunteers was more likely to still walk a quarter of a mile (without a walker)? That's right. When it came to avoiding "major mobility disability" which the researchers defined as becoming unable to walk 400 meters or more a structured exercise program was better than a program of healthy aging education. Specifically, the researchers found that 30% of the exercisers experienced a period of major disability, compared to 35.5% of the seniors enrolled in the healthy aging education program. This is a very encouraging finding! That said, it's also a bit sobering to realize that even with exercise, almost 1 in 3 older adults experienced a period of limited mobility, of which half lasted 6 months or more. In this post, I'll share some more details on this study, because the results provide a wonderful wealth of information that can be helpful to older adults, family caregivers, and even geriatricians such as myself. Want to know how often the exercisers experienced "adverse events"? (Hint: often!) Wondering just what the structured exercise program involved? (Hint: more than walking!) Let's dig into the details! At the end of this post, I'll share my list of key take-home points for older adults and family caregivers. Who were the study volunteers? Whenever you read about a research study, it's important to understand how the study volunteers compare to the older adults in *your* life. One of...

input with options: Read the following context and answer the question. Context: For active people, regular training is as important part of maintaining and increasing fitness. About the only real downside to regular exercise is the transient toll it takes on the body after a hard training session. The pain and soreness after training needs sufficient time to recover from before another hard session can be performed. A very plausible theory pushed for many years is that the post-exercise oxidative stress in the body is the primary cause of the muscle damage and fatigue experienced. If you could reduce this oxidative stress, then it would allow quicker recovery, and then more time spent training. What this theory ignores though is that oxidative damage is a natural part of how the body adapts to stressful exercise, allowing the body to repair and grow stronger to allow higher levels of performance in the future. A small scale study has previously found that trained and untrained individuals who dose up on antioxidant supplements impair important exercise training adaptations such as improved insulin sensitivity and production of oxidative stress defence proteins. Now researchers have extended this study by looking at the effect of antioxidants in trained female runners, and published their findings in the European Journal of Sports Science. Twenty-three well trained female runners took part in three separate 3-week training blocks where they took either 1 gram of vitamin C, blackcurrant juice, or a placebo drink for each of the training blocks. Each of the dietary interventions involved drinking a similar volume of fruit drink of a total of half a litre per day split over the morning and evening. The training performance of each runner was carefully measured at the beginning and end of each 3-week treatment period. The runners stuck to a set training schedule which allowed a more accurate assessment of any changes in performance over the training period. Question: What do many people think causes muscle damage and fatigue in the body? Answer:
OPTIONS:
- eating too many carbs before a run
- post-exercise oxidative stress
- not enough information
- eating too much fat before a run
output:
post-exercise oxidative stress
