Q: At least Raheem Morris finally has the name of the Bucs' starting quarterback in the back of his mind.
 He wants to make sure he made the decision with his head and not just his heart.
 That's why Morris declined to name his choice between Byron Leftwich and Luke McCown on Friday until after one last consultation with his coaching staff.
 After that  Morris said  he would inform the owners  then his team before making the eagerly awaited announcement. Players were off Friday  so an announcement could come this morning.
 "We'll have a decision here in the near future " Morris said. "I think we've got to go with who we think gives us the best chance to win.
A: Raheem Morris
Rationale: Here the main entity is Raheem  Morris since the main topic of the document is about him starting as quarterback.
Q: The fourth quarter has historically not been a particularly busy period for missile tests for the North  according to  Harry Kazianis  director of defense studies at the Center for the National Interest  a Washington think tank founded by former President Richard Nixon .
"When we look at the data on the fourth quarter of most years they either test anywhere between zero and two "  he  said. "Last year they did two tests."
Kazianis said there are a lot of contributing factors for why the hermit regime doesn't do as many tests in the final quarter of the year. They include having the military assist in the fall harvest due to North Korea's chronic food shortages. Also   he  said December is when the North tends to conduct more military drills.
"North Korea is just occupied doing other things  but they also have to continue proving their missile technology "  he  said. "So I'm not shocked that they did this test but I'm a little surprised since I thought they would hold off until the Olympics."
Indeed   Kazianis  said there's every expectation that the first quarter will produce "a heavy testing cycle" as has been the case with Pyongyang's ballistic missile program.  He  said the North "has a ton of new technology " including long-range ballistic missiles and "new types of heat-shield technology."
According to  Kazianis   the North has "a lot of goodies that they will start rolling out. This situation is going to get worse. The testing is going to get more rigorous. We're really at just the tip of the iceberg of seeing their capabilities  to be honest."
