Which of the following is one of the friendship rules identified in a study by communication researchers argyle and henderson? a. don't tell your friend information that might hurt his or her feelings. b. don't be jealous of your friend's other friends. c. routinely tell your friend that you care about him or her. d. protect your friend from potential threats.

The following is one of the friendship rules identified in a study by communication researchers Michael Argyle and Monika Henderson:

B. Don't be jealous of your friend's other friends.

Explanation:

Michael Argyle and Monika Henderson conducted a study and were able to identify rules for successful friendship, one of those rules was, "Don't be jealous of your friend's other friends."

In "The Rules of Friendship" Journal of Social and Personal Relationships (1984), Argyle and Henderson found some of the following 'rules', "...“should not be jealous of other’s relationships,” “help in time of need,” “respect the friend’s privacy,” “confide in each other,” and “stand up for the other person in their absence."

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).

the earthquake in haiti was a magnitude of 7.0 according to the u.s geological survey yet the smaller earthquake in haiti killed more than 200,000 and left more than 1.2 million people homeless. the chile earthquake was a magnitude of 8.8 and 500 times more stronger but chile's earthquake only injured 712 people.
