I. Poor scale, wasted space

III. No units for dependent variable

Explanation:

Given

See attachment for graph

Required

Identify the mistakes

The mistakes are

(I) Poor scale

The unused space on the vertical axis is much. A better scale would have reduced the amount of unused space.

(II) There is a unit (1 minute) in the independent variable; so, this is not a mistake

(III) No unit on the dependent variable

Yes, this is part of the mistake, as there is no units on the x-axis

(IV) Decimals

This is not a compulsory requirement of plotting graphs; so, this is also not a mistake

Hence,

Hence (I) and (III) are mistakes on the graph

the answer is c a tornado
