Even though each item on the distance ladder is only effective within a certain distance range,
the concept is still effective because
A) distances are ultimately relative, and not absolute.
B)each technique produces exact distances on its own.
C)each step can be calibrated through its overlap with the previous step.
D)the distance ladder concept can be verified by looking in different wavelength ranges,
E)the time delay due to light travel time is significant enough to limit the accuracy of distance measurements anyway.

Engineers find 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. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
