Answer:
B. The competition between Cope and Marsh pushed each man to make amazing discoveries.
Step-by-step explanation:
A paleontologist refers to an expert (individual) who is saddled with the responsibility of studying the various forms of life that were in existence during geologic or prehistoric ages through the use of fossils.
We know that influence is a function of how much power a person has to affect, control or manipulate another person so as to cause a change in the person's action or activity.
Hence, the sentence which best describes how two paleontologists influenced each other is; the competition between Cope and Marsh pushed each man to make amazing discoveries.
