Task: Question Answering
Input (English): Passage: MacBook Air -- Apple incorporated several features in the design of the MacBook Air, such as the reduction of lead to make it more environmentally friendly. The MacBook Air contains no BFRs and PVC wiring, meets Energy Star 5.0 requirements, has a recyclable enclosure, and is rated EPEAT Gold. Its display is made from arsenic-free glass, and contains no mercury. To reduce the computer's size and weight, several features were sacrificed. It was Apple's first notebook since the PowerBook 2400c without a built-in removable media drive. It also omits a FireWire port, Ethernet port, line-in, media card slots (except the 13'' 2010 through 2015 models, which have an SD card slot), and a Kensington Security Slot.
Question: does a macbook air have an ethernet port
