Question

in the late 1880s, inventors nikola tesla and thomas edison were competing with each other. edison had developed direct current (dc), which is current that runs in a single direction. at that time, direct current was the standard form of electricity in the united states. tesla, however, had developed alternating current (ac), which reverses direction. as opposed to dc, which cannot be easily converted to lower or higher voltages, ac can be converted to different voltages with a transformer. edison didnt want to lose money on his dc patents, so he spread false information suggesting that ac was dangerous. over the years, though, ac won out as the method of choice. today, ac—not dc—provides the majority of our electricity.
was developed by edison
runs in a single direction
can easily be converted to different voltages
provides most electricity today

Explanation:

To solve this, we analyze each statement with the given information:

1. "Was developed by Edison": From the text, "Edison had developed direct current (DC)". So this matches DC.
2. "Runs in a single direction": The text says "direct current (DC), which is current that runs in a single direction". So this matches DC.
3. "Can easily be converted to different voltages": The text states "AC can be converted to different voltages with a transformer" (and DC cannot). So this matches AC.
4. "Provides most electricity today": The text says "Today, AC—not DC—provides the majority of our electricity". So this matches AC.

We can organize this into a table:

Statement	DC	AC
Runs in a single direction	✔️	❌
Can easily be converted to different voltages	❌	✔️
Provides most electricity today	❌	✔️

(If the task was to fill the table, the above shows the correct mappings. For each row, mark the column (DC or AC) that applies.)
