Q: A decrease in greenhouse gas levels decreases global temperature and an increase raises global temperature.  Having read the above passage, choose the right answer to the following question (choices are go up or go down ):   If you are able to add greenhouse gases the temperature will go up or go down?
A: go up


Q: The longer the resistor, the more resistance it has.  Having read the above passage, choose the right answer to the following question (choices are first one or second one ):   Chris needs a resistor for a science experiment he is conducting in class. He needs it to have the greatest resistance possible. If the second resistor is twice as long as the first one, then the first one or second one will have the greater resistance?
A: second one


Q: The greater the objects mass, the greater the force of attraction; in addition, the greater the distance between objects, the smaller the force of attraction.  Having read the above passage, choose the right answer to the following question (choices are greater or lesser ):   Dave dropped a feather and a ball out of a window. The ball landed last because it had mass that, compared to the feather, was greater or lesser?
A: lesser


Q: At higher temperatures, particles of reactants have more energy, so they move faster.  Having read the above passage, choose the right answer to the following question (choices are faster or slower ):   When observing reactants and their particles, Shane increases the temperature they're exposed to, noting that they now move faster or slower?
A: faster
