Vying for Vacays

[aalriy]

The Marsden family is traveling through Europe on vacation and has two days to spend in Barcelona. While planning the daily activities, each family member has fairly strong preferences. Little brother asked to go to the beach at least one of the days, but cannot walk for more than 4 hours during a day. Mom loves shopping for local crafts so requested shopping activities on both days. Big sister will get credit for school so she must visit at least 4 art or architectural sites during the family’s visit, but Dad said he could not stand to visit more than one art exhibit on a single day. The family has 12 hours each day to devote to activities, and they have already decided on the following.

Day 1:
Park Güell (Art Exhibit, Bicycle, 3 hours)
Catalunya en Miniatura (Entertainment, Walking, 1 hour)
Olympic Stadium (Sightseeing, Bicycle Tour, 4 hours)
Las Ramblas (Shopping, Bus Tour, 3 hours)

Day 2:
La Segrada Familia (Architecture, Walking, 3 hours)
Barri Gotico (Shopping, Bicycle Tour, 2 hours)
Aeri del Port (Sightseeing, Cable Car, 4 hours)
Nova Icària (Beach, Walking, 1 hour)

Select an activity that can be added to the schedule for the first day. Then select an activity that could be added to the schedule for the second day. Make only two selections, one in each column.

Additional Day 1 Additional Day 2 Activity
Mirador De Colon (Architecture, Walking, 1 hour)
Poble Espanyol (Shopping, Walking 2 hours)
Montserrat (Sightseeing, Bus Tour, 1 hours)
Museu Picasso (Art Museum, Walking, 2 hours)
Mar Bella (Ocean, Boat Outing, 4 hours)
La Pedrera (Art Museum, Walking, 1 hours)

According to the explanation the correct answer for an additional activity on the second day is Montserrat, but it does not meet the criteria of at least 4 art or architecture activities during the 2 days

My best guess is that whoever wrote the question considered Olympic Stadium an architecture site but forgot to designate it as such. Nevertheless, you can rule out all the wrong choices on this one, and if you carefully examine the question you will see that there is technically nothing preventing the family from pulling a one-hour, no walking art museum out of thin air and adding it to the list. so while the explanation is not consistent with what was given in the problem, the problem itself and the answers stand up to scrutiny. keep in mind, you're just being asked what can be added to the schedule, not what will COMPLETE the schedule..

Tim,

Like aairly, I too was thrown off by the Sister constraint, which by your careful reasoning, amounts to a red herring.

I find nothing wrong with your response to aairly, but the "Show Explanation" for this problem clearly states that one of the constraints is "Minimum of 3 art or architecture activities".

This directly contradicts the problem statement of "at least 4" such activities. While the problem can remain as-is, with its devilish inclusion of the unnecessary Sister constraint, the answer explanation needs to be changed to be consistent.

I have not seen this problem yet, but could it be that the explanation says that sister still needs to add a "minimum of 3 art or architecture activities" since she only has one on the schedule now and needs 4? Again, I haven't seen the problem but I'm speculating since that seems like an odd error to make.

Jamie,

The problem appeared on my 6th CAT. If mgmat, like the real thing, hardcodes the IR questions (as opposed to dynamically assigning them) then "vying for vacays" appears for everyone's 6th IR?

To answer your question, no, there are already two on the schedule. The answer explanation is clearly not in sync with the problem statement.

Edit: replace jnelson with Jamie

[tim]

as i've already mentioned, there are some issues with the explanation, but last i checked the problem and correct answer were still legit. do you believe this not to be the case?
