Correct Answer:
A
In order to answer this logic problem, it might be best to start with a clear list of the constraints:
- 12 hours = total hours available
- 4 hours = total hours for walking
- Minimum 4 art or architecture activities during the 2 days
- Maximum 1 art museum per day
- Minimum of 1 beach activity during the trip
- Minimum of 1 shopping activity each day
Now we can start with the activities the family has already planned to see what has been accomplished from the list and what has not. On Day 1, the family has already planned 11 hours of activities, and only 1 hour of walking. Therefore there is only 1 hour left to plan, and they could choose a walking activity if they would like. On Day 2, the family has planned 9 hours of activities with 4 hours of walking. This means that there are 3 hours they can use for activities but they cannot include walking.
Using these 2 constraints, we see that the only activities possible for each day are the following:
Day 1: Mirador De Colon, Montserrat, or La Pedrera
Day 2: Montserrat
Therefore, the family must choose the sightseeing trip to Montserrat on Day 2, leaving only Mirador De Colon and La Pedrera for Day 1. If we now look at the family preferences, we see that Mom already has her shopping on each day (Las Ramblas and Barri Gotico) and Little Brother has his beach activity on Day 2 (Nova Icària), but Big Sister only has 3 of her 4 art or architecture activities. Both Mirador De Colon and La Pedrera fit this category, but Dad will not go to more than 1 art exhibit on a single day, and the family will already visit Park Güell on Day 1. This means that they cannot visit La Pedrera as well. Therefore, the family will visit Mirador De Colon on Day 1.
