Question: Planet Y and planet X were two inhabited planets in a nearby solar system. People from Planet X were living in harmony with nature, and didn't hurt the environment in any way. People on planet Y generated lots of air pollution, and destroyed their ozone layer by using inappropriate substances. Given the paragraph above, please answer correctly the following question: Which planet used fewer aerosol sprays? Hint: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk.
Answer: planet X
[Q]: The hospital in Y city had a good disposal site in which they disposed of Biomedical wastes, but the hospital in the neighboring city X had big problems, because the biomedical waste contaminated the ground water and affected the population. Given the paragraph above, please answer correctly the following question: Which city had a higher incidence of respiratory problems? Hint: One of the most adverse impacts of poor waste management, especially municipal waste, is the incidence and prevalence of diseases such as malaria and respiratory problems, as well as other illnesses through the contamination of ground water. Biomedical wastes pose great danger in Bangladesh too as a report estimated that 20% of the biomedical waste is "highly infectious" and is a hazard since it is often disposed of into the sewage system or drains.[6] Such poor sanitation has serious consequences for the health of the residents and a report suggests that "most of the child mortality could be related with this problem".[7] With regards to the living standards, solid waste leads to blockage in the drainage system which leads to flooding in the streets. Consequently, mosquitoes and bad odour are among the negative impacts resulted.[7]

input: Please answer the following: Local hospital has launched a program to check if a patient has Retinitis. Resident ophthalmologist David is in charge of this program. In the first day of the program he checked two patients, patient A and patient B. The test result showed that patient A had Retinitis, but patient B did not have Retinitis. Then next day David checked two other patients, patient C and patient D. Patient C was 40 years old, but patient D was 80 years old. He found both patient C and D had Retinitis. Given the paragraph above, please answer correctly the following question: Which patient is in risk of becoming blind, patient A or patient B? Hint: Retinitis is inflammation of the retina in the eye, which can permanently damage the retina and lead to blindness. The retina is the part of your eye that is also known as the "sensing tissue." Retinitis may be caused by a number of different infectious agents. Retinitis, also called Retinitis pigmentosa, has a prevalence of one in every 2,500-7,000 people. This condition is one of the leading causes that leads to blindness in patients in the age range of 2060 years old.

Please answer this: Bob works as a scientist for a large fishing company in Norway. Norway's government has strict regulations on fishing to protect its fish stock. Part of Bob's job is to provide the government with fish mortality data. Today, he has two samples of fish to investigate, sample A and sample B. Bob concluded sample A had natural mortality, but sample B had fishing mortality. Given the paragraph above, please answer correctly the following question: For which sample predation would be one of the causes of death, sample A or sample B? Hint: Fish mortality is a parameter used in fisheries population dynamics to account for the loss of fish in a fish stock through death. The mortality can be divided into two types: Natural mortality: the removal of fish from the stock due to causes not associated with fishing. Such causes can include disease, competition, cannibalism, old age, predation, pollution or any other natural factor that causes the death of fish. In fisheries models natural mortality is denoted by (M).[1] Fishing mortality: the removal of fish from the stock due to fishing activities using any fishing gear.[1] It is denoted by (F) in fisheries models.

Answer: sample A
Problem: two buildings had different tenants. Building Y had many seniors over 65 years of age, and building X had individuals under 65 years old. Given the paragraph above, please answer correctly the following question: Which building had fewer people that have more time for their hobbies? Hint: Old age begins in the mid-60s and lasts until the end of life. Most people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common.

A: building X
input: Please answer the following: Bill and Chris are passionate entomologists. Bill knows everything there is to know about most ants except the Leafcutter ants. Chris studied Leafcutter ants extensively and exclusively for years now. They are good friends and exchange ideas often over a pint of beer. Given the paragraph above, please answer correctly the following question: Which friend studied more about generalist predatory ants? Hint: Most ants are generalist predators, scavengers, and indirect herbivores, but a few have evolved specialised ways of obtaining nutrition. It is believed that many ant species that engage in indirect herbivory rely on specialized symbiosis with their gut microbes to upgrade the nutritional value of the food they collect and allow them to survive in nitrogen poor regions, such as rainforest canopies. Leafcutter ants (Atta and Acromyrmex) feed exclusively on a fungus that grows only within their colonies. They continually collect leaves which are taken to the colony, cut into tiny pieces and placed in fungal gardens. Ergates specialise in related tasks according to their sizes. The largest ants cut stalks, smaller workers chew the leaves and the smallest tend the fungus. Leafcutter ants are sensitive enough to recognise the reaction of the fungus to different plant material, apparently detecting chemical signals from the fungus. If a particular type of leaf is found to be toxic to the fungus, the colony will no longer collect it. The ants feed on structures produced by the fungi called gongylidia. Symbiotic bacteria on the exterior surface of the ants produce antibiotics that kill bacteria introduced into the nest that may harm the fungi.
