CR 1000 paradox

by amitu » Tue Jun 29, 2010 6:15 am
Adults who work outside the home spend, on average, 100 minutes less time each week in preparing dinner than adults who do not work outside the home. But, contrary to expectation, comparison show that the dinners eaten at home by the two groups of adults do not differ significantly with respect to nutritional value, variety of menus, or number of courses.
Which one of the following, if true, most helps to resolve the apparent discrepancy in the information above?
(A) The fat content of the dinners eaten at home by adults who do not work outside the home is 25 percent higher than national guidelines recommend.
(B) Adults who do not work the home tend to prepare breakfast more often than adults who work outside the home.
(C) Adults who work outside the home spend 2 hours less time per day on all household responsibilities, including dinner preparation, than do adults who do not work outside the home.
(D) Adults who work outside the home eat dinner at home 20 percent less often than do adults who do not work outside the home.
(E) Adults who work outside the home are less likely to plan dinner menus well in advance than are adults who do not work outside the home.

OA to come , want to have disussion on this ?

FACT 1: Adults who work outside spend 100 mins less time in preparing dinner than those who do not.
FACT 2: Both dinners do not differ w.r.t. nutritional value, variety or number of courses.

These are two seemingly strange facts. What would explain why this happens?

A. This "25% above the guideline" would be the same even for those who do work outside the home according to Fact 2. So it doesn't explain why it is equal.

B. So the ones who spend 100 mins more make breakfast MORE often. We are talking about dinner!

C. Household responsibilities are irrelevant.

D. So the ones who take 100 mins less time, are eating dinner 20% less often at home. This explains why they spend this 100 mins less per week to prepare meals, since they are eating out. This also explains how they are able to maintain the nutrition, variety, etc. (since they are eating at restaurants)

E. Planning the menus does not affect the two facts and why they seem to contradict eachother.

Pick D.
