Answer:
The correct answers that fills the gaps are: short run; cannot alter them.
Explanation:
- Fixed costs: fixed costs cannot be altered in the short term. They mainly include things like rent, technology, etc., that require time to change, and are often associated with indirect production costs (everything that is not a direct production factor). They do not depend on the level of production and cannot be adjusted accordingly.
- Variable costs: variable costs depend on the level of production, and may include things such as productive factors (raw materials) and labor (not including fixed wages).
