Can someone help me with this

B. How important memory strategies can be

Explanation:

by describing these techniques as "a lifesaver" the author is saying they are very important.

A Cannot be true because the author is saying that being able to use these strategies is a valuable thing not something that is too heavily relied on.

C cannot be true because this statement has nothing to do with the frequency at which people use memory strategies.

D cannot be true because the author is expressing that memory strategies can be essential so the importance is not exaggerated.

there were a lot of changes in wars like that and thing evolved

explanation:

i decided to stay late in the laboratory to continue my experiment with the lightbulb. at midnight, thomas edison opened the door and walked in with his head held high.

1. he leaned on the wall and observed me carefully.

2. his harsh scrutiny made me self-conscious of my skills in the lab.

3. perhaps it was just me, but the air in the laboratory began to thicken as i found myself having difficulty to breathe.

4. i turned to look at him fully as i mentally prepared myself for what my very first words would be to thomas edison.

5. the next couple of seconds shocked me. it wasn't me who spoke, but rather him and with diction i could never think of using in a simple sentence.
