Since the invention of digital readout, machine designers have rushed to replace conventional dials and gauges with digital units. Yet the digital gauge has drawbacks in some situations. Since it presents an exact numeric value, it must be decoded and analyzed by a human operator; its meaning cannot be read in an instantaneous scanning. An analog dial or gauge can be marked with red to alert the operator when a value is entering a danger zone; a digital gauge cannot. And it is difficult to tell whether a digital readout is increasing or decreasing over time, while the up or down movement of a pointer on an analog gauge can be quickly and easily observed.
The author of the passage above would probably recommend the use of digital gauge in cases when
I. warning of a sudden rise or fall in value is needed
II. an operator must read and interpret several gauges within a few seconds
III. a precise numeric value is essential
(A) I only
(B) III only
(C) I and III only
(D) II and III only
(E) I, II, and III

I said B.
My notes:
Replace conventional dials with digital dials
digital gauge can't notify you about alerts -- it can provide you a numeric estimate
Hard for humans to analyze digital gauges (increase/decrease)
Hence, Option I is out because analyzing the increases or decreases of a digital gauge is difficult for the human operator.
I eliminated Option II as well since the numeric values that a digital gauge provides takes more than a few seconds to understand as mentioned in the paragraph. "Its meaning cannot be read in an instantaneous scanning"
This provides evidence for Option III

Notes:

Opt B
