### HideShow timer Statistics

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 go with (B) III only

I. warning of a sudden rise or fall in value is needed

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.

I take this to mean that digital gauges are not good to alert for danger.

II. an operator must read and interpret several gauges within a few seconds

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.

Digital values are not good if you need to interpret the informatin quickly.

III. a precise numeric value is essential

Since it presents an exact numeric value

Definitely B.
I. warning of a sudden rise or fall in value is needed
This contradicts with "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."

II. an operator must read and interpret several gauges within a few seconds
This contradicts with "its [digital gauge's] meaning cannot be read in an instantaneous scanning."

III. a precise numeric value is essential
This conforms with "it [digital gauge] presents an exact numeric value"
