Article: The health benefits of dogs can result from contact with dogs in general, and not solely from having dogs as pets. For example, when in the presence of a pet dog, people show reductions in cardiovascular, behavioral, and psychological indicators of anxiety. Other health benefits are gained from exposure to immune-stimulating microorganisms, which, according to the hygiene hypothesis, can protect against allergies and autoimmune diseases. The benefits of contact with a dog also include social support, as dogs are able to not only provide companionship and social support themselves, but also to act as facilitators of social interactions between humans. One study indicated that wheelchair users experience more positive social interactions with strangers when they are accompanied by a dog than when they are not. In 2015, a study found that pet owners were significantly more likely to get to know people in their neighborhood than non-pet owners.

Question: What is lessened when people are with their pet dogs?
Ans: anxiety


Article: Iran has a paramilitary, volunteer militia force within the IRGC, called the Basij, which includes about 90,000 full-time, active-duty uniformed members. Up to 11 million men and women are members of the Basij who could potentially be called up for service; GlobalSecurity.org estimates Iran could mobilize "up to one million men". This would be among the largest troop mobilizations in the world. In 2007, Iran's military spending represented 2.6% of the GDP or $102 per capita, the lowest figure of the Persian Gulf nations. Iran's military doctrine is based on deterrence. In 2014 arms spending the country spent $15 billion and was outspent by the states of the Gulf Cooperation Council by a factor of 13.

Question: How many full-time members does the Basij have?

Article: The influence of science also began appearing more commonly in poetry and literature during the Enlightenment. Some poetry became infused with scientific metaphor and imagery, while other poems were written directly about scientific topics. Sir Richard Blackmore committed the Newtonian system to verse in Creation, a Philosophical Poem in Seven Books (1712). After Newton's death in 1727, poems were composed in his honour for decades. James Thomson (1700–1748) penned his "Poem to the Memory of Newton," which mourned the loss of Newton, but also praised his science and legacy.

Question: Who penned a poem called "Poem to the Memory of Newton" to mourn the loss and praise the legacy of Newton?

Article: Han-era medical physicians believed that the human body was subject to the same forces of nature that governed the greater universe, namely the cosmological cycles of yin and yang and the five phases. Each organ of the body was associated with a particular phase. Illness was viewed as a sign that qi or "vital energy" channels leading to a certain organ had been disrupted. Thus, Han-era physicians prescribed medicine that was believed to counteract this imbalance. For example, since the wood phase was believed to promote the fire phase, medicinal ingredients associated with the wood phase could be used to heal an organ associated with the fire phase. To this end, the physician Zhang Zhongjing (c. 150–c. 219 AD) prescribed regulated diets rich in certain foods that were thought to cure specific illnesses. These are now known to be nutrition disorders caused by the lack of certain vitamins consumed in one's diet. Besides dieting, Han physicians also prescribed moxibustion, acupuncture, and calisthenics as methods of maintaining one's health. When surgery was performed by the physician Hua Tuo (d. 208 AD), he used anesthesia to numb his patients' pain and prescribed a rubbing ointment that allegedly sped the process of healing surgical wounds.

Question: What was used during surgery to relieve patients of their pain?
Ans:
anesthesia
