问题 What is the possible reason that some foods promote the brain performance? [br]  
Why certain food choices might help the brain function better remains unclear. Perhaps these regimens’ known cardiovascular benefits, which promote a good flow of blood and oxygen to the brain, are key. But other factors may be at work. Of course, questions about when these dietary changes need to happen or how diet stacks up against other factors, such as physical activity, sleep patterns and genetics also remain unanswered.
Sports gambling is illegal nearly everywhere except Nevada. But a 2006 federal act barring unlawful online gambling exempts fantasy sports, designating it a game of skill. On Oct. 15, however, Nevada officials ruled that daily fantasy was indeed a form of wagering and prevented sites from operating there without gaming licenses. Members of Congress have also called for hearings on the legality of daily fantasy.

选项 A、an unlawful gambling
B、a game of skill
C、a form of gambling
D、a potential industry

答案 C

解析 内华达州对梦幻体育的态度可谓一波三折。先是在2006年禁止非法网络游戏时,确定它是一种技能游戏。今年又宣布它实际上是一种赌博形式,而且就它的合法性,即将召开听证会。fantasy sports(可译为梦幻体育、幻想体育)是一种网络游戏,玩家可像球队经理一样把现实中的职业运动员组成虚拟的队,各队之间的比赛分数源于现实中真实的体育比赛数据。fantasy sports在美国盛行,正在向全球蔓延,现已涉嫌赌博。wager意为“赌博”;hearings“听证会”。
