If the winner of a promotional contest is selected by a lottery, the lottery must be fair, giving all entrants an equal chance of winning. Since 90 percent of the winners selected by the lottery in a recent promotional contest submitted their entry forms within the first 2 days of the 30-day registration period, it is clear that this lottery did not meet the fairness requirement.

Summarize Argument
The author concludes the lottery didn’t give all entrants an equal chance of winning. Why not? Because 90 percent of the people who won had entered within the first 2 days of the registration period, which was 30 days long.

Notable Assumptions
The author assumes the lottery gave early entrants a more-than-even chance of winning, and that’s why most people who won had entered early. In particular, this means assuming that significantly fewer than 90 percent of the total entries were submitted within the first 2 days.

A
The family members of the organizer of the contest were not permitted to participate in the contest.
This is irrelevant. It makes no claim about the timing of lottery entries or the selection process. If anything, it suggests the lottery is more likely to have been fair, not less.
B
The manner in which the contest winner would be selected was publicized prior to the selection of the winner.
This is irrelevant. It doesn’t say that method gave any early entrants a higher chance of winning.
C
The contest entry forms were submitted at a consistent rate throughout the registration period.
This makes concrete the author’s primary assumption: that fewer than 90 percent of the total entries were submitted in the first two days. It makes it less likely that pure chance caused most of the winners to be early entrants.
D
The rules of the contest were posted conspicuously by those who organized the contest.
This is irrelevant. It doesn’t say those rules gave early entrants a better chance of winning than late entrants.
E
The number of people entering the contest far exceeded the expectations of the contest organizers.
This is irrelevant. It doesn’t imply the lottery organizers selected winners before the contest ended, or that they gave early entrants a better chance of winning.
