He had a small, basic golf facility installed at Camp David, and became close friends with the Augusta National Chairman Clifford Roberts, inviting Roberts to stay at the White House on several occasions. Roberts, an investment broker, also handled the Eisenhower family's investments. Roberts also advised Eisenhower on tax aspects of publishing his memoirs, which proved financially lucrative.

Input: Read this: Before scrimmage, an official places the ball at the spot it was at the stop of clock, but no nearer than 24 yards from the sideline or 1 yard from the goal line. The line parallel to the goal line passing through the ball (line from sideline to sideline for the length of the ball) is referred to as the line of scrimmage. This line is similar to "no-man's land"; players must stay on their respective sides of this line until the play has begun again. For a scrimmage to be valid the team in possession of the football must have seven players, excluding the quarterback, within one yard of the line of scrimmage. The defending team must stay a yard or more back from the line of scrimmage.
Question: Where must an official stay until a play has begun again?

Output: unanswerable


Input: Read this: Tort law covers the entire imaginable spectrum of wrongs which humans can inflict upon each other, and of course, partially overlaps with wrongs also punishable by criminal law. Although the American Law Institute has attempted to standardize tort law through the development of several versions of the Restatement of Torts, many states have chosen to adopt only certain sections of the Restatements and to reject others. Thus, because of its immense size and diversity, American tort law cannot be easily summarized.
Question: What is the Restatement of Torts not successfull as a whole yet?

Output:
many states have chosen to adopt only certain sections
