TIMED TEST;

What do effective study environments include? Select four options.

1:a great deal of light
2:a well-organized setup
3:a number of distractions
4:an array of electronic equipment
5:a flat surface for reading or writing
6:comfortable seating arrangements

1,2,4,(5 or 6)

Explanation:

In my opinion 1,2, and 4 are all pretty essential, but these options all depend on the person. 3 just does not make sense since you wouldn't want any interruptions and  5 or 6 are built off of preference. For me personally I prefer studying on a bed or laying down, which are not always the flattest of surfaces.

1,2,4,6

I think this because 1,2, and 4 are all pretty essential, but these options all depend on the person. 3 just does not make sense since you wouldn't want any interruptions and i think its 6 because you need to be comfortable

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.
