### HideShow timer Statistics

Statistics over four consecutive years showed that four percent
more automobile accidents happened in California during the week
following the switch to daylight saving time and during the week
following the switch back to standard time than occurred the week
before each event. These statistics show that these time changes
adversely affect the alertness of California divers.

The conclusion in the argument above is based on which of the
following assumptions?

(A) Drivers in California as well as those in the rest of the United
States have similar driving patterns.
(B) The observed increases in accident rates are due almost entirely
to an increase in the number of minor accidents.
(C) Four years is not a sufficiently long period of time over which
to judge the phenomenon described.
(D) There are no other factors such as school vacations or holiday
celebration that cause accident rates to rise during these weeks.
(E) A time change at any other time of years would not produce a
similar increase in accident rates.
