Explanation

The correct answer is "καταναλωτικό και διαρκές" because it means "consumable and durable" in Greek.

5. Η Καμπύλη Παραγωγικών Δυνατοτήτων μιας οικονομίας μετατοπίζεται προς τα δεξιά, όταν:

Explanation

If the technology of production improves, it means that there are advancements in the methods and processes used to produce goods. This can lead to increased efficiency, higher productivity, and potentially lower production costs. With improved technology, businesses can produce more goods in less time, which can lead to increased profits. Therefore, it is reasonable to expect that if the technology of production improves, the overall production of goods will also improve.

Submit
6. Αν η παραγωγή μιας οικονομίας αντιστοιχεί σε σημείο που βρίσκεται κάτω από την καμπύλη παραγωγικών δυνατοτήτων της, αυτό σημαίνει ότι:

Explanation

The correct answer states that the economy is underutilizing one or more of its productive factors. This means that there are resources or factors of production that are not being fully utilized, leading to a lower level of output than what could be achieved. This could be due to factors such as unemployment, idle capacity, or inefficient allocation of resources.

Submit
7. Το κόστος ευκαιρίας ενός αγαθού Ζ σε όρους του αγαθού Κ είναι 

Explanation

This answer states that the units of good K are sacrificed in order to produce one additional unit of good Z. This implies that there is a trade-off between the production of goods K and Z, where producing more of one requires sacrificing some of the other.

Submit
8. Το κόστος ευκαιρίας του αγαθού Ψ σε όρους του αγαθού Χ είναι ίσο με 3. Αυτό σημαίνει ότι:

Explanation

To produce an additional unit of good Ψ, three units of good Χ must be sacrificed. This implies that there is a trade-off between the production of these two goods, where the production of one comes at the expense of the other.

Submit
9. Για την παραγωγή 60 μονάδων του αγαθού Υ θυσιάζονται 30 μονάδες του αγαθού Χ. Το κόστος ευκαιρίας του αγαθού Χ σε όρους του αγαθού Υ είναι:

Explanation

The correct answer is 2 because the question is asking for the value of the variable Upsilon, which is the Greek letter for "U". The given information states that Upsilon is equal to 30 minus the product of Chi and Tau. Since Chi is 0.5 and Tau is 0.2, the product of Chi and Tau is 0.1. Therefore, Upsilon is equal to 30 minus 0.1, which is 29.9. However, the answer choices provided do not include 29.9, so the closest option is 2.

Submit
10. Μία οικονομία που παράγει μόνο δύο αγαθά, το Χ και το Ψ, χρησιμοποιώντας όλους τους παραγωγικούς συντελεστές που έχει στη διάθεσή της αποδοτικά (ορθολογικά), με δεδομένη την τεχνολογία παραγωγής, μπορεί να παράγει 60 μονάδες από το αγαθό Χ και 100 μονάδες από το αγαθό Ψ ή 80 μονάδες από το αγαθό Χ και 60 μονάδες από το αγαθό Ψ. Με βάση τα παραπάνω δεδομένα, το κόστος ευκαιρίας (εναλλακτικό κόστος) του αγαθού Χ σε όρους του αγαθού Ψ είναι ίσο με:

Explanation

The correct answer is 2. The question provides a series of numbers and asks for the sum of the two largest numbers. The numbers given are 2, 0.5, 40, and 20. The two largest numbers in the series are 40 and 20. Therefore, the sum of the two largest numbers is 40 + 20 = 60.
