Read the research question. why do high school students not spend enough time doing physical activity each day? which statement is the best evaluation of the research question? it is too biased; this research question contains an opinion and cannot be answered through research. it is clear and complex; this research question has a single focus that can be researched and discussed. it is too broad; this research question is unfocused and would be too difficult to discuss in a single research essay. it is too narrow; this research question is limited to high school students, which is not a large enough group to research.

The correct answer is:

A.) It is too biased; this research question contains an opinion and cannot be answered through research.

It is clear and complex; this research question has a single focus that can be researched and discussed is the correct answer.

Explanation:

The question has a very particular goal (to know why high school students don't do a lot of exercise), and even though it would be very difficult (if not impossible) to get an answer per every student, it is also possible to select a group of people that represents the whole picture. It would have to be a group big enough to discuss the question in an essay and to be more than the author's group of friends or classmates. Also, a part of discussing the question is to see if the hypothesis is correct or not, which could end showing that high school students do spend time doing physical activity.

i believe the answer is: b. mr. head had a long, tube-like face with a rounded open jaw and a short depressed nose.

this is because in the un-revised sentence it said that mr. heads face was long and tube-like, and he had a rounded open jaw. this is not a very grammatically correct because of how it seems to drag on with the and, replaced with, with, makes it sound more fluent in the description.
