la Read the first paragraph of an article about electric cars. According to the writer, what is the main
problem associated with these cars?

I would love electric cars to work, but they have their problems and the 9
biggest of these is battery technology. Portable electronic gadgets like
laptops, mobiles and cameras have long suffered from the limitations
