Question

16. You must wear your goggles in the laboratory

to improve your vision

sometimes

to avoid myopia

when instructed to do so

Answer 1

Eliminate A, and B. What do you think it is? Guess :)

Answer 2

I would say D is your best bet. C. is a problem with you eyes though

Answer 3

to improve vision and avoid myopia, duh!

Answer 4

I can confirm that "to improve your vision" isn't it, since my goggles turn into a foggy mess the moment I get near a lab station!

In all seriousness, goggles are used to protect your eyes from damage. You should *ALWAYS* be wearing goggles in the lab environment (that's what they teach here at Rose, at least).

"To avoid myopia" sounds wrong at first glance, since nearsightedness is largely a hereditary condition. However, injuries to the eye *CAN* cause myopia, so it makes sense. I'd go with that choice- the others are either silly or irresponsible (choices B and D are practically identical, too).

fire blanket

Answer 13

Argh, I hated fire-blanket questions back in middle school lab!

"A handy chemical" is vague and doesn't really have any meaning, so you can scratch that out.

"The wind from running" is a terrible idea! Oxygen *fuels* fires!

A fire extinguisher would technically work, but it's a bad idea to get the foam into people's eyes/mouth/nose etc.

Therefore, I would use a fire blanket in this situation. It's safe and effective at snuffing out small fires.
