Answer:
B) Is not a contract because there is no consideration for B's promise.
Explanation:
In contract law, consideration is the benefit that must be bargained for between the parties involved. It is the essential reason for the parties entering a contact. Consideration must have some value and is exchanged on the performance or promise from the other party.
Common law rules on contract modifications require some new consideration in order to modify an existing contract. In this case, only B added some new consideration (more money) to the written contract, A didn't add anything new.
Answer:
The answer is B: At the midpoint of the project, members realize that their behavior pattern must change in order to complete the project on time.
Explanation:
Punctuated equilibrium is a concept in both biology and business where long periods of relative stability are often followed by growth spurts.
The punctuated-equilibrium model argues that groups usually move forward during bursts of change after going for long periods without change.
In the answer B, this concept is captured as group members of a project realise somewhere at the midpoint, that their behavior pattern must change in order to complete the project on time.
This shows that a period of relative stability was observed and then a short period of growth will be observed during the project lifecycle. This agrees with the development pattern known as punctuated equilibrium.
Answer:
Option 4 is definitely correct: Whether real GDP increased cannot be determined with the information given.
Explanation:
The information that is given only states that there has been an increase in the market value of final goods and services in two years. So, we cannot conclude that production increased in Rushya or average price levels increased there as per Option A and C respectively, because market value can be increased by both increase in production or price levels. Even Option B cannot be concluded as the real GDP is dependent on other variables as compared to the total market value.
Thus, only appropriate statement is option D: we cannot determine increase in real GDP with the given information.
