Question

the muse asked tyler about \disagreements\ with other paleoartists. based on this excerpt, what is one reason for these differences?
a there is not enough scientific evidence available for a paleoartist to be certain about one idea or another.
b paleoartists do not base their models of prehistoric creatures on actual anatomy which leads to debates.
c artists are naturally creative, and they do not want to base their ideas on the work of anyone else.
d scientific evidence does not exist to help tyler and other paleoartists know the anatomy of the animals.

muse: are there disagreements among paleoartists?
tyler: there are a few unsettled debates in paleoart, which make for interesting exercises in imagination. did predatory dinosaurs have lips or lipless, crocodile - like jaws? did the plant - eating dinosaurs like triceratops have cheeks? how high or low did the long - necked sauropods hold their necks? there are lots of ideas, and some scientific evidence, but still some uncertainty.

Explanation:

• Option A: Tyler says there are "some scientific evidence, but still some uncertainty" and mentions unsettled debates (like dinosaur lips, cheeks, neck position). This matches "not enough scientific evidence for certainty".
• Option B: Paleoartists do base on anatomy (implied by scientific evidence use), so B is wrong.
• Option C: The excerpt doesn't mention artists not wanting to base on others' work, so C is wrong.
• Option D: Tyler says there is some scientific evidence, so D's "does not exist" is wrong.

Answer:

A. There is not enough scientific evidence available for a paleoartist to be certain about one idea or another.
