See stage-1 for the rules.

4 variables here (D, E, F, G). Get all 4 right to get 1 point.

D was a famous syntax convention invented much, much later by famous programmer **E during **his employment at F. Although D and B sound similar the connection between the two is, at best, a play on words. The only similarity between D and B is that both are named after the nation-of-origin of their creator. C and F on the other hand, have had a fairly long and fairly amenable relationship. C and F teamed up hoping to pre-empt the announcement of device G last year, but that flopped. Although they hit the market a month before G, no one heard of their device.
