James watson’s discovery of the base pairings in the dna helix was a result of trial and error. he discovered that adenine pairs with thymine and that guanine pairs with cytosine after he continually attempted to align models of the bases in other combinations. which best describes how this example illustrates creativity?

No choices were provided, but the best description of James Watson's discovery of the DNA base pairs as an illustration of creativity is that through his trial and error approach, Watson was willing try out different things and explore the unknown. Creativity works the same way, allowing us to create something extraordinary out of ordinary.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
