Here is a question about this article: In 1913 the Zliten mosaic, a Roman mosaic famous for its many scenes from gladiatorial contests, hunting and everyday life, was discovered in the Libyan town of Zliten.

Problem: Please answer a question about the following article about Gymnastics:
Individual routines in trampolining involve a build-up phase during which the gymnast jumps repeatedly to achieve height, followed by a sequence of ten bounces without pause during which the gymnast performs a sequence of aerial skills. Routines are marked out of a maximum score of 10 points. Additional points (with no maximum at the highest levels of competition) can be earned depending on the difficulty of the moves and the length of time taken to complete the ten skills which is an indication of the average height of the jumps. In high level competitions, there are two preliminary routines, one which has only two moves scored for difficulty and one where the athlete is free to perform any routine. This is followed by a final routine which is optional. Some competitions restart the score from zero for the finals, other add the final score to the preliminary results.
In high level competitions how many preliminary rountines are there?
A: two preliminary routines

The United States Army is made up of three components: the active component, the Regular Army; and two reserve components, the Army National Guard and the Army Reserve. Both reserve components are primarily composed of part-time soldiers who train once a month, known as battle assemblies or unit training assemblies (UTAs), and conduct two to three weeks of annual training each year. Both the Regular Army and the Army Reserve are organized under Title 10 of the United States Code, while the National Guard is organized under Title 32. While the Army National Guard is organized, trained and equipped as a component of the U.S. Army, when it is not in federal service it is under the command of individual state and territorial governors; the District of Columbia National Guard, however, reports to the U.S. President, not the district's mayor, even when not federalized. Any or all of the National Guard can be federalized by presidential order and against the governor's wishes.
Who does the D.C. National Guard report to?
the U.S. President
