user: input question: Background: 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.  Paragraph: Toronto is home to one of the leading manufacturers of aerosol sprays in the country. Because of this, homes in Toronto often spray high levels of aerosol on a regular basis. In Saskatchewan, meanwhile, the local government enacted a ban on aerosol sprays several years ago, so their level of aerosol use is now essentially zero.  Given the paragraph above, please answer correctly the following question: Which city, Toronto or Saskatchewan, will be contributing less to skin cancer risk????
output answer: Saskatchewan

input question: Background: The Keystone XL Pipeline would transport oil from the oil sands in Alberta, Canada. The oil would travel into the United States. In the U.S. it would be refined. The pipeline is controversial. A leak could cause damage to wildlife habitat. A leak could also release enough oil to contaminate the Ogallala Aquifer. The Aquifer is crucial to agriculture and urban development in the Midwestern U.S. When burned, the fuel from the oil sands would increase pollutants. Greenhouse gases into the atmosphere would increase. The future of the pipeline is currently on hold.  Paragraph: Lawmakers were debating the pros and cons of Keystone XL Pipeline. One group of lawmakers proposed that the pipeline be constructed. They put their proposal in proposal A. The rival group of lawmakers proposed that the pipeline should not be build. They put their proposal in proposal B. Lawmakers would now have to choose one of the proposals.  Given the paragraph above, please answer correctly the following question: Which proposal would result in more pollutants, proposal A or proposal B????
output answer: proposal A

input question: Background: The Tasmanian devil is a nocturnal and crepuscular hunter, spending the days in dense bush or in a hole.[64] It has been speculated that nocturnalism may have been adopted to avoid predation by eagles and humans.[65] Young devils are predominantly crepuscular.[66] There is no evidence of torpor.[67]  Young devils can climb trees, but this becomes more difficult as they grow larger.[68][69] Devils can scale trees of trunk diameter larger than 40 cm (16 in), which tend to have no small side branches to hang onto, up to a height of around 2.5–3 m (8.2–9.8 ft). Devils that are yet to reach maturity can climb shrubs to a height of 4 metres (13.1 ft), and can climb a tree to 7 m (23 ft) if it is not vertical.[70] Adult devils may eat young devils if they are very hungry, so this climbing behaviour may be an adaptation to allow young devils to escape.[71] Devils can also swim and have been observed crossing rivers that are 50 metres (160 ft) in width, including icy cold waterways, apparently enthusiastically.  Paragraph: The scientists examined both the Eastern and the Western slopes of the mountain. They reached the conclusion that the Western slope was inhabited by many more adult Tasmanian devils than the Eastern slope.  Given the paragraph above, please answer correctly the following question: Which slope had more devils climbing shrubs up 4 meters high????
output answer: Eastern

input question: Background: Plates include both oceanic crust and continental crust. Stable subduction zones involve the oceanic lithosphere of one plate sliding beneath the continental or oceanic lithosphere of another plate due to the higher density of the oceanic lithosphere. That is, the subducted lithosphere is always oceanic while the overriding lithosphere may or may not be oceanic. Subduction zones are sites that usually have a high rate of volcanism and earthquakes.[2][better source needed] Furthermore, subduction zones develop belts of deformation and metamorphism in the subducting crust, whose exhumation is part of orogeny and also leads to mountain building in addition to collisional thickening.  Paragraph: David is interested in geology. One day he was studying about how the earth's crust works. He specifically noticed two lithosphere, lithosphere A an lithosphere B. Lithosphere A is an oceanic lithosphere while lithosphere B is an overriding lithosphere. He also noticed two  distinct zones, zone A an zone B. Zone A is a subduction zone, but zone B is not a subduction zone. Just reading about geology made David excited. Now, he wants to  visit places with high volcanic activity. For that he chose place C. To compare with place C geology he would also visit place D, which does not have any volcanic activity.  Given the paragraph above, please answer correctly the following question: Would place D most likely be located or not located  in zone A????
output answer:

assistant: not located
