Problem: Given the question: You are given a new situation: Two villages were situated on different sides of the hill. Each village has its own approach to agriculture. East village decided to clear the land, by felling many trees and bushes, and set up a vast irrigation system. West village too a more natural approach to food production and applied the edible forest method, and all the permaculture principles over the years.  and a hint : Groundwater salinization compromises buffering properties. Vegetation clearance, along with irrigation, causes serious issues. Irrigation increases the water table and mobilizes salts, and vegetation clearance allows it to come in contact with water habitats and vegetation. This stresses species not adapted to high salinity. High levels of salinity reduces water uptake in plants, by causing stomatal closure, reducing photosynthesis. Forests undergo decline in areas of high salinity and shallow groundwater depths because these conditions make them more susceptible to droughts. Forests undergo decline in areas of high salinity and shallow groundwater depths making them more susceptible to droughts.  Please answer this question : Which village had fewer problems with groundwater salinization?

The answer is:
West


Problem: Given the question: You are given a new situation: Mary's dog just gave birth to a litter of puppies! As of right now the puppies eyes are closed so they can't see. They require the mother to take very close care of them while they grow to keep them safe.  and a hint : Organisms can use different strategies to increase their reproduction rate. Altricial organisms are helpless at birth, and their parents give them a lot of care. This care is often seen in bird species. ( Figure below ). Altricial birds are usually born blind and without feathers. Compared to precocial organisms, altricial organisms have a longer period of development before they reach maturity. Precocial organisms, such as the geese shown below, can take care of themselves at birth and do not require help from their parents ( Figure below ). In order to reproduce as much as possible, altricial and precocial organisms must use very different strategies.  Please answer this question : Will an altricial animal have a higher or lower chance of survival with no care from a parent?
++++++++++++++++++++++++++++++++
The answer is:
lower


Problem: Given the question: You are given a new situation: Hill town was full of gasoline powered vehicles, while Valley town 50 miles away, banned all gas powered vehicles and allows only electrical vehicles or horse-and-buggies.  and a hint : Gasoline-powered vehicles emit a lot of harmful materials. Nitrogen oxides are formed when atmospheric nitrogen reacts with oxygen at the high temperatures found in a car engine. Carbon monoxide is a by-product of incomplete combustion of hydrocarbons. Evaporated and unused fuel releases volatile hydrocarbons into the atmosphere to help form smog. The presence of a catalytic converter in the exhaust system of the car causes these materials to react and be changed into less harmful products.  Please answer this question : Which town emitted less carbon monoxide?
