Ques: Answer the following question given this paragraph: Does everyone who smokes develop lung cancer? No, of course not. Is it possible to get lung cancer without smoking? Sadly, yes it is. That's not to say there is no relationship between the two: smoking is still the leading cause of lung cancer. But it does suggest that a person's genetic background has a role in this process. Apart form true single gene disorders, environmental factors, or environmental triggers , may determine the development of disease in individuals genetically predisposed to a particular condition. Environmental triggers may include stress, physical and mental abuse, diet, exposure to toxins, pathogens, and radiation. Many cancers are thought to have an environmental component. It has been suggested that environmental factors play a role in autism as well. Asthma is obviously triggered under certain environmental conditions. Q: Many cancers, as well as autism, are thought to have what component, which is certainly a factor in asthma? Choices: - emotional - critical - ecological - environmental A:
Ans: environmental

Ques: Answer the following question given this paragraph: Electromagnetism is magnetism produced by an electric current. When electric current flows through a wire, it creates a magnetic field that surrounds the wire in circles. You can see this in the diagram below. Note that electric current is conventionally shown moving from positive to negative electric potential, as in this diagram. However, electrons in current actually flow in the opposite direction, from negative to positive potential. Q: When electric current flows through a wire, it creates what type of field that surrounds the wire in circles? Choices: - gravitational - kinetic - thermal - magnetic A:
Ans: magnetic

Ques: Answer the following question given this paragraph: The immune system naturally becomes less effective as people get older. This is why older people are generally more susceptible to disease. Q: What system gets less effective with age, that generally makes older people more disease susceptible? Choices: - infectious system - reproductive system - nervous system - immune system A:
Ans: immune system

The Universe includes all of space and time. Q: What branch of science is the study of the universe, not of cosmetics? Choices: - theology - astronomy - epistemology - cosmology A:
