Answer:
(in my own words)
1. Definition: to concentrate, or to control
2. Definition: a connection between two ends.
3. Definition: a direct connection between a starting point to it's ending point.
Explanation:
1. Think of the context: "to channel his anger." Imagine surfing through the channels of a TV. You keep going until you find the right channel, or in this case of the sentence exempt, the "right channel" to "control/concentrate" one's feelings.
2. Imagine a line, starting at point A ending to C. In between those lines, say the middle, is point B. Point A can direct to Point B for any resources that A might need, and same goes for Point C.
3. Similar to (2), we will use the same sense of connecting two points. However, in this case, it is only a line, or a channel, connecting Points A-B. A direct connection.
