14. Most authors of scientific texts use -person point of view to show that they're presenting evidence objectively .

Most authors of scientific text use evidence objectively.

EVIDENCE OBJECTIVELY:

They have proof that can be tested with the same results from a scientific perspective, methods of investigation must employ observable, empirical, and quantitative evidence while being based on rules of reasoning that are explicit and particular." Science collects evidence through observation and experimentation, and theories are formed and tested.

OBJECTIVELY:

Based on their observations so, by defining what objective evidence isn't. The terms 'pass' or 'fail' are no and never are objective proof; the words "yes," "no," "as expected" and "true" and "false." They are findings. You conclude on the basis of what you think the objective proof demonstrates.

The above question is kind of confusing if you are asking true/false?  I would say false because of the point of view in question.
