Answer the question based on the following text.

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 less dissolved oxygen 80 degrees fahrenheit or 70 degrees fahrenheit? 


Text:

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.
