prompter: Which of the following elbows are the most wet?
A. A kilogram of feathers
2) Coach Malibu
D - The cross-section of air

assistant: Your question contains some errors - firstly, none of the multiple-choice answers appear to relate to the question "Which of the following elbows are the most wet?". Secondly, each of the multiple-choice answers are formatted differently - you should consider reformatting the question if it is to be used on any kind of exam or survey.

In response to the question, the option`2) Coach Malibu` is the only answer that appears to refer to a person with elbows, so that is my final answer.

prompter: if i were to put this question into a formal exam environment specifically in the late teen age range (school years 10-12) what could it be used to test? and what are some likely responses? assuming standard distribution of minorities and a American public school

assistant: Please rephrase the question with more detail.
There are no obvious relationships between the options.

prompter: I just wanted to see how you responded to unclear instructions. Give me a description of what I could have meant by "the cross-section of air".

assistant: Air as such is a mixture of gases and thus does not have a defined size or cross section. However, it may be possible to define a cross section of air via the cross section of Earth's atmosphere from a point of view in outer space; this would likely not be well-defined though since Earth's atmosphere does not have a clear boundary. Of course, when talking about air in a specific region of space or in a container a cross section can be easily calculated.

In a more general sense a cross section can also refer to the cross section of individual molecules, atoms, or particles. For example, for each molecule present in Earth's atmosphere (nitrogen, oxygen, etc.) a cross section can be determined. The cross section of air could then be defined as the average cross section of the molecules, weighted by the percentage of those molecules in Earth's atmosphere. Note that in the realm of quantum physics a cross section is not defined by size but rather by the probability of an interaction occurring (in the case of air whether two molecules exchange energy and momentum by "bouncing off of each other").

assistant: It is very difficult to deduce what you have meant by the phrase "the cross-section of air" without further context. The simple answer is: I don't know. 
However, if you insist, I can try and imagine an answer but note that it will be purely fictional and may not be based in reality. Do you still wish me to give you a description of what "the cross-section of air" could mean?

assistant: If you were attempting to measure the amount of flow through an opening, like in a tube, the "cross-section of air" could refer to the hollow cross section, through which air can travel and which at any given moment is occupied by some mass of air if the object is in an atmosphere.

assistant: None of the items listed are physical options that normally get wet.

prompter: Are you saying a kilogram of feathers is unlikely to get wet?

assistant: While it is possible that feathers or any of the things listed may get wet, the question does not make sense, as non of the listed items are elbows and the list does not use the same format throughout.  Can you please rewrite the question so that I can try to answer?

assistant: When considering feathers, they are typically covered with a hydrophobic coating (e.g. thin fatty film). Hence, the feathers are unlikely to get wet by themselves. 

Additionally, if a kilogram of feathers got wet (e.g. the coating failed), the absorbed water would add to mass, making it no longer a kilogram.

assistant: A kilogram of feathers can get wet, but that is not what you asked in the your first question. You were just trying to mess with me ;)

Is there anything else you'd like to throw at me?
