What is a primary difference between a standard corded line trimmer and a brushless battery-powered trimmer?

• A. It operates without a cord
• B. It uses gasoline
• C. It has significantly lower safety
• D. It cannot be used indoors

Answer: (A)

The main idea here is how the tool is powered. A standard corded line trimmer gets its electricity through a cord plugged into an outlet, so your movement is limited by the length of the cord and you have to manage the cord while trimming. A brushless battery-powered trimmer runs on a rechargeable battery, letting you operate without any cord—hands-free freedom to move and reach around obstacles. The brushless design improves efficiency and longevity, but the key difference the question is asking about is the lack of a cord, which defines cordless operation. Gasoline-powered trimmers use a different fuel source entirely, and indoor use is not inherently restricted for cordless electric models with proper ventilation and safety practices, so those aren’t the defining difference.
