A CORTO PLAZO
A CORTO PLAZO POR QUE NO SE VA A DEMORAR
Y MANDA TUS NUDOS
The answer is "short-term goal."
A "goal" is an objective that a person sets to achieve in the future. It could be tomorrow, this week, next month or in the years to come. Achieving goals largely depends on the type of goal you are pursuing.
In the case above, Maria is planning for a "short-term" goal. This kind of goal can be achieved in a short span of time, such as a few days or months (no longer than 6 months). The history project that she is planning will surely take place in the near future, since Maria is a student. Contests that are announced, usually don't take place more than 6 months from the time of the announcement.
So, in this case, the goal that Maria sets is a short-term goal.
