The design of a new computer processor requires that electric current be carefully controlled. Why might an engineer want to use
Leya [2.2K]
Because metalloids are semiconductors. The fact that metalloids are brittle/shiny are only physical characteristics and wouldn’t be the reason why a metalloid would be helpful for designing a new computer processor. Amphoteric means that it’s able to react both as a base and as an acid, but since the computer processor has to have something to do with electricity, the second option would be the answer. Semiconductors are also helpful for electrical circuits, so that’s also why is would be best for the new computer processor.

<u>Attached below is the missing excerpt </u>

<em>I knew I could never let Mom hear the messages, because protecting her is one of my most important raisons d’être, so what I did was I took Dad’s emergency money from on top of his dresser, and I went to the Radio Shack on Amsterdam. It was on a TV there that I saw that the first building had fallen. I bought the exact same phone and ran home and recorded our greeting from the first phone onto it. I wrapped up the old phone in the scarf that Grandma was never able to finish because of my privacy, and I put that in a grocery bag, and I put that in a box, and I put that in another box, and I put that under a bunch of stuff in my closet, like my jewelry workbench and albums of foreign currencies. </em>
