Step 1: Recall the test:
The 4x10 m Shuttle Run has a short course and a very short time of effort, usually under 30 seconds.
Step 2: Match component to test:
Very short and fast efforts with many turns test how quickly a person changes direction. That is agility, along with running speed.
Step 3: Rule out the rest:
A jump test shows leg power. A sit and reach or shoulder test shows flexibility. A long run shows endurance. The shuttle run is none of these.
Step 4: Pick the answer:
Only option (2) names agility and speed together.
Final Answer:
The test is used to find agility and speed, option (2).
\[ \boxed{\text{Agility and speed}} \]
