Q: (CNN) -- For about 13 minutes, Team USA sat at the top of its World Cup soccer group, ahead of the mighty Germany and star-powered Portugal. Then Portugal struck back. With seconds left to play, Cristiano Ronaldo set up a header for his teammate Silvestre Varela, leaving the final score tied at 2-2. It was a harsh blow for the Americans, but it does not end their World Cup dreams -- it just makes them harder to achieve. With every team in Brazil now having played two matches, most groups now have clear winners and losers. But not Group G. In theory, any of the four teams in the group of Germany, the United States, Ghana and Portugal could still qualify for the knockout round.Sunday's tie with Portugal makes it more difficult for USA to achieve its World Cup dreamsThe Americans secure a place if they beat or draw with GermanyNetherlands tops Group B with victory over ChileNEW: Brazil, Mexico advance to the Round of 16 with convincing victories 
 Question:No matter who wins the Ghana-_ match, neither team can end up with more than four points.

A: Portugal
