The study abroad alien marvin, who lives in san francisco, has been asked to host a teenage alien, regor, as part of an intergalactic exchange program. marvin is sure that regor would love to experience the adventure of sailing, but decides he should introduce the concept of a "sailboat" first. marvin tries to describe the common features of a sailboat. he explains that they are pointed at the front and square at the back, have a tall mast to hold up the sail, and have one or two triangular sails. which of the following demonstrates a problem with this approach? a. some sailboats have more than one mast and more than two sails. b. this description does not describe a specific sailboat. c. this description does not provide an average of all relevant features. d. some sailboats are longer than others.

The correct answer is:

a. Some sailboats have more than one mast and more than two sails.

Explanation:

The main problem regarding the approach above is that is describing a specific kind of sailboat, however in general terms, it is possible to find them with more than one mast and more than two sails as it is mentioned in Marvin's description. In my opinion, the explanation about a sailboat by Marvin is also missing the purpose of the boat itself and also how it works, to offer a more general and clear idea about the concept.

Marvin could have also mentioned that sailboats are small boats that can be used to travel over the water using the wind`s energy to impulse it through the mast and the sails.

you probably know the answer. stop asking stupid questions and making me waste my time. j.k. ; )   b.t.w. what are three ratios equivalent to 5 : 11? thx
