Answer 1

Tysm PsyDAG!!! That was the only question left to my test, tysmmmm I got a 100%!! Without your help, I would have failed :(.

Answer 2

Missing one question is not failure. It's human.

Answer 3

I thought I would fail since this was a 4 question test, and I thought that if I got one wrong, I would get a 75%, but thx for the encouragement!

Answer 4

It's a benchmark review question, sorry for not adding that 😅

Answer 5

First let me say that I am pleased that you made a 100% on that test. Second, I am pleased that PsyDAG came to your rescue. However, I want to ask why you would have failed the test. I want to ask why common sense wouldn't have served you well. Here are the choices and my comments.
F. The mass of the lemon juice decreases. <b>Wouldn't common sense tell you that the amount (1 oz, 2 oz, whatever) of the lemon juice added to the water would not change? Where is it going. What would happen to make it disappear? </b>

G. The water becomes a solid<b> What makes you think that adding lemon juice to water would make the water freeze?</b>

H. The lemon juice dissolves and spreads out evenly in the water
J. The volume of the water decreases<b> Same as the lemon juice disappearing. The water could evaporate but that won't happen very fast.</b>
Next. So the only answer that is left is the correct one and that's the common sense one. I think students sometimes give up on a test question when a little common sense would help them make a better grade. Good luck in your future tests.
