HELLO, Sir.
I am always appreciated your good lecture.
But, here I have some questions on Quiz.

It's About  No. 6 in Module 4/ No.2 & 5 in Mudule 5. 
I am very embarrassed and confused now that I have no idea where can I find the "exact" answers through online classes(video) even though I watch them again and again to check!

For example,  No.5 in Mudule 5. 
Teacher says that Using real objects can be very useful especially for lower level students and we can practice not only nouns but also tense, structures...etc. But I can't find it is the "easiest way to each concepts and practice structures or not."

Those kinds of questions make me.... like push me to play picture puzzle. 
Am I not good at playing picture puzzle? Where can I find your mention about those answers?
(Frankly speaking, I hope I don't need to find "hiding" one sentence teacher mentioned to answer quiz. Just I wish I can do it if I understand important points of the lessons.) 

Or should I select answers with my own thought?
Of course, after taking lessons, I could "guess" which was "may" be answers.
But, It is test.
We have to select answers that teacher "admit". That means teacher have to mention about the answers with "exact words or sentences."

Please, help me.
What am I wrong?
Every test, I am trouble with this kind of problem.

Thank you for reading.
I think you may feel annoyed by it.
But, I really don't know what should I do in every test time. So, please please understand and help me.
