Question

Batteries have three parts: an anode, cathode and electrolyte. Electrons build up at the anode, the negative end. Because electrons have the same charge, they repel each other. In a closed circuit, there’s a path for them to take to get to a place with fewer electrons: the cathode, or the positive end. When using batteries, don’t ever directly connect the negative end to the positive end. That will create a short circuit. The wire will get very hot, you might burn yourself and the battery will lose energy quickly.

In which detail does the author provide a reason not to connect the negative end of a battery to the positive end directly?

A
“...the battery will lose energy quickly.”

B
“... there’s a path for them to take...”

C
“... they repel each other.”

D
“Electrons build up at the anode...”

Answer 1

The detail that provides a reason not to connect the negative end of a battery to the positive end directly is:

A “...the battery will lose energy quickly.”

This statement explains a consequence of creating a short circuit, which emphasizes why such a connection should be avoided.
