How many power sources are listed for electrical power?

• A. 7
• B. 6
• C. 5
• D. 4

Answer: (A)

The key idea is to identify and count every distinct power source that’s listed for electrical power. To figure the total, scan the list or diagram and tally each unique source once, making sure not to double-count anything that appears more than once or to lump multiple sources together unless they’re clearly listed separately. In this item, there are seven distinct sources named, so the total number of power sources is seven. If you’d seen fewer, it would mean one or more sources weren’t counted individually—perhaps they were grouped together or one line wasn’t read carefully.
