Engineers create a new metal that is stronger than steel but much lighter. This material is also significantly cheaper than what is currently used for
most aircraft, available in large quantities, and easy to manufacture. What is
the best step for the engineers to make next?
A. Design a new airplane with this new material.
B. Build a new plane with this material.
C. Decide what profit margins they would like to see for this new
technology.
D. Test the new airplane in a wind tunnel test.

Malik formed a hypothesis that an increase in atmospheric oxygen levels by 10% would cause red-legged grasshoppers to grow larger than normal. suppose that malik performs an experiment to test his hypothesis. which of these actions would represent a scientific mistake in his experiment? a. he experiments on live grasshoppers instead of preserved ones. b. he focuses on red-legged grasshoppers instead of all kinds of grasshoppers. c. he varies the nitrogen and carbon dioxide levels in the air from one trial to the next. d. he conducts the experiment in a controlled lab setting with a lab partner. e. he measures the mass and length of his specimens at the start of each trial.
