Passage: "For decades, many small islands depended on diesel generators that ran only a few hours each night. Fuel had to be shipped in by boat, so electricity was expensive and stopped whenever storms delayed deliveries. Solar panels combined with batteries are changing this. Once installed, they need no fuel, and the batteries store daytime energy for use at night. The equipment still costs money to buy and maintain, but several island communities now enjoy power around the clock for the first time." Which statement can be inferred from the passage?
Correct answer: D. Solar power with batteries makes island communities less dependent on fuel deliveries.
Since solar systems need no fuel once installed, communities no longer depend on boats bringing diesel. The passage directly says the equipment still costs money, so the second option is false.
