[EX Q]: Question: Mary is taking measurements of the amount of oxygen in samples of water. If she measured the total levels of dissolved oxygen in a sample at 70 degrees fahrenheit and compared it to a sample at 80 degrees fahrenheit, which would contain more dissolved oxygen? 
 Option1: 80 degrees fahrenheit 
 Option2: 70 degrees fahrenheit 
 Explanation: Warm water cant hold as much dissolved oxygen as cool water, so an increase in the temperature of water decreases the amount of oxygen it contains.
[EX A]: 70 degrees fahrenheit
