The dorsal attention network is one of two sensory orienting systems in the human brain, and this complex network signals where a human's attention should be focused. The dorsal attention network shows activity increases after a presentation of cues indicating what subjects should direct their attention to.

The statements above, if true, best support which of the following assertions?

(A) The dorsal attention network is the primary sensory orienting system in the human brain.
(B) Relative to the dorsal attention network, other sensory orienting systems do not demonstrate the same degree of activity increases after exposure to a presentation of cues.
(C) Where human attention is focused is always predictable given a particular activity increase, and the degree of exposure.
(D)Activity in a human's dorsal attention network is lower preceding a presentation of cues as to where to focus that human's attention.
(E) The two human sensory orienting systems play equal roles in determining where human attention should be focused.

We need to find what agrees with the statement.

Premise: the dorsal attention network signals where a human's attention should be focused.

Option A - Incorrect
The argument states it to be a complex network and not a primary orienting system in the human brain.

Option B - Incorrect
Here, the argument is only concerned about the dorsal attention; any other network aside thus, is outside the scope of the argument.

Option C - Incorrect
If true, then is no indication or evidence to back this up in the argument.

Option D - Correct
If the dorsal attention network activity increases "after" a presentation of cues indicating what subjects they should direct their attention to, it means that it is lower when it "precedes" the presentation of cues to where to focus that human's attention.

Option E - Incorrect
We are only concerned about one of the sensory orienting systems, which is the dorsal attention network and not the equal roles they play in the human brain.
