Under the vascular heading are migraine and cluster headaches. Migraine, the most debilitating common form, afflicts perhaps 18 million Americans who collectively lose 64 million workdays a year and cost the nation about \$50 billion in lost work time and medical expenses. A migraine, afflicting more women than men, usually affects one side of the head, lasts for hours or days and may recur as infrequently as once every other month or as often as once a week. Migraine is often accompanied by nausea, perspiring and sensitivity to sound and light.

shouldn't it be "costs" to agree in number with noun (Migraine)

good question and i know you are intimited by the migrain.
the subject of the verb "cost" is not migrain.
the subject is "who". who refers to those migrain afflicted 18 mil people.

Migraine, the most debilitating common form of headache, afflicts perhaps 18 million Americans, who collectively lose 64 million workdays a year, and they cost the nation \$50 billion in medical expenses and lost work time.

(A) year, and they cost the nation \$50 billion in medical expenses and lost - they can refer to 'Americans' or 'workdays'

(B) year and thus cost the nation \$50 billion in medical expenses and lost - thus is correct here. Americans lose workdays and thus (therefore) cost the nation \$50 billion (CORRECT)

(C) year, so as to cost the nation \$50 billion in medical expenses and lost - 'so as to' is almost always incorrect in GMAT

(D) year that costs the nation \$50 billion in lost medical expenses and - 'that' refers to year which is incorrect. The loss of \$64 billion dollars is because of the loss of workdays and not because of 'year'

(E) year, which thus cost the nation \$50 billion in lost medical expenses and - 'which incorrectly refers to 'year'

(A) year, and they cost the nation \$50 billion in medical expenses and lost
", and they" makes the construction awkwrd. If they refers to the Americans then there is no need for the comma... Also, "they" should not be used... Look at the structure: "...afflicts blah blah Americans, who lose blah blah in a year and [they] cost.." NOT PARALLEL..

(B) year and thus cost the nation \$50 billion in medical expenses and lost
CORRECT. "who collectivelu lose blah blah and thus cost the nation blah blah" simply modifies Americans

(C) year, so as to cost the nation \$50 billion in medical expenses and lost
"Migraine afflicts a number of Americans, who are blah blah in a year, so as to cost the nation..." changes the meaning by making the cost look intentional...

(D) year that costs the nation \$50 billion in lost medical expenses and
misplaced modifier by touch-rule

(E) year, which thus cost the nation \$50 billion in lost medical expenses and
"who collectively lose 64 million workdays a year, which costs..." is OUT because of misplaced modifier.
