Question: Question: You are given a new situation: Two people got stuck in a local  blizzard. Tom had a bottle of alcohol with him and drank it after he found some kind of shelter in the snow. Dan didn't have alcohol with him.  and a hint : Alcoholic beverages do not make the entire body warmer.[361] The reason that alcoholic drinks create the sensation of warmth is that they cause blood vessels to dilate and stimulate nerve endings near the surface of the skin with an influx of warm blood. This can actually result in making the core body temperature lower, as it allows for easier heat exchange with a cold external environment.  Please answer this question : Which of the two people had a larger influx of warm blood near the surface of the skin?
Answer: Tom

Question: You are given a new situation: The island of Utopia is a popular tourist destination with its great sandy beaches. Two of the most popular beaches are beach A and beach B. Both beaches also have  large wildlife sanctuaries where rare dolphins can be seen. There are some fisheries in both beaches too. This year the government of Utopia is looking for more sources to increase their revenue. They decided to allow sand mining in beach A next year, and earn  some extra revenue.  and a hint : Sand mining is a direct cause of erosion, and impacts the local wildlife.[2] Various animals depend on sandy beaches for nesting clutches, and mining has led to the near extinction of gharials (a species of crocodile) in India. Disturbance of underwater and coastal sand causes turbidity in the water, which is harmful for organisms like coral that need sunlight. It can also destroy fisheries, financially harming their operators.  Removal of physical coastal barriers, such as dunes, sometimes leads to flooding of beachside communities, and the destruction of picturesque beaches causes tourism to dissipate. Sand mining is regulated by law in many places, but is often done illegally.[3] Globally, it is a $70 billion industry, with sand selling at up to $90 per cubic yard.[4]  Please answer this question : In which beach fisheries might financially struggle next year, beach A or beach B?
Answer: beach A

Question: You are given a new situation: Jim's dad is a scientist. While his dad is out working he goes to the lab in the basement and find an electroscope. The electroscope is currently in a neutral state. He then grabs a nearby rod that is positively charged and moves it near the knob of the electroscope. Fascinated he sees the leaves of the electroscope move apart from each other.  and a hint : Similar to the results of a negatively charged rod, if a positively charged rod is brought near the knob of a neutral electroscope, it will attract some electrons up from the leaves onto the knob. That process causes both of the leaves to be positively charged (excess protons), and the leaves will diverge. If the positively charged rob is actually touched to the knob, the rob will remove some electrons and then when the rob is removed, the electroscope will remain positively charged. This is a permanent positive charge.  Please answer this question : Given the rod was negatively charged when it touched the neutral electroscope, would the electroscope have a positive or negative charge?
Answer:
Answer: negative
