Answer:
1. - Observer
2. - iterator
3. - strategy
4. - composite
5. - decorator
Explanation:
An object contains other objects (elements) and must give access to them for clients, without exposing its internal structure. This is an observation.
The subject-object can generate events as an iterable (iterator) and could use different strategic algorithms to achieve a task. Class objects can be used to aggregate other class objects.
In python, the decorator function mimics the outer function of a nested function, but still maintains the functionality of the second function

Answer: a. intrapersonal and short-term goals
Explanation:
Intrapersonal goals are those that we set for ourselves in our minds to accomplish. The students that are finishing their homework after school most probably set that goal in their minds and so meeting it would mean meeting their intrapersonal goals.
Homework is not a long term project but rather a short one that is usually meant to be completed within days. Completing it is therefore a short term goal.
The students who finish their homework after school are therefore accomplishing both their intrapersonal and short-term goals.
