[EX Q]: There are several reasons an otherwise valid and agreed upon treaty may be rejected as a binding international agreement, most of which involve problems created at the formation of the treaty.[citation needed] For example, the serial Japan-Korea treaties of 1905, 1907 and 1910 were protested; and they were confirmed as "already null and void" in the 1965 Treaty on Basic Relations between Japan and the Republic of Korea.

[EX Q]: The materialist view is perhaps best understood in its opposition to the doctrines of immaterial substance applied to the mind historically, famously by René Descartes.

[EX Q]: Denver took the opening kickoff and started out strong with Peyton Manning completing an 18-yard pass to tight end Owen Daniels and a 22-yard throw to receiver Andre Caldwell. A pair of carries by C. J. Anderson moved the ball up 20 yards to the Panthers 14-yard line, but Carolina's defense dug in over the next three plays. First, linebacker Shaq Thompson tackled Ronnie Hillman for a 3-yard loss. Then after an incompletion, Thomas Davis tackled Anderson for a 1-yard gain on third down, forcing Denver to settle for a 3–0 lead on a Brandon McManus 34-yard field goal. The score marked the first time in the entire postseason that Carolina was facing a deficit.
[EX A]:
What team received the opening kickoff?
