Q: passage: In the canonical case, lawyers seeking admission must earn a Juris Doctor degree from a law school approved by the jurisdiction, and then pass a bar exam administered by it. Typically, there is also a character and fitness evaluation, which includes a background check. However, there are exceptions to each of these requirements. A lawyer who is admitted in one state is not automatically allowed to practice in any other. Some states have reciprocal agreements that allow attorneys from other states to practice without sitting for another full bar exam; such agreements differ significantly among the states.
 question: do you need to graduate law school to take the bar exam?

A: Yes

Q: passage: For a thin lens in air, the focal length is the distance from the center of the lens to the principal foci (or focal points) of the lens. For a converging lens (for example a convex lens), the focal length is positive, and is the distance at which a beam of collimated light will be focused to a single spot. For a diverging lens (for example a concave lens), the focal length is negative, and is the distance to the point from which a collimated beam appears to be diverging after passing through the lens.
 question: is the focal length of a convex lens negative?

A:
No
