CORRECT WORD: Put the correct words from a–d below in the article.

A team of US researchers has come (1) ____ with an electricity system that does not need wires. This is a breakthrough (2) ____ what will hopefully be a wireless future. The scientists, from the Massachusetts Institute of Technology, (3) ____ a 60-watt light bulb using magnetic fields. In the test, the power source was just two metres away from the light, but the team hopes they will soon be able to send electricity longer distances through the air. They have (4) ____ their new invention “WiTricity”, or wireless electricity. Although wi-fi has been around for (5) ____ years now, it has been limited to the transmission of information, especially between computers and modems, printers and scanners.
