Which set оf pаths prоvides pоssible bаsis pаths for this control flow diagram? Expand to view the image description The image shows a control flow diagram that begins with a single circular start node at the top. The start node flows downward into a decision node represented by a diamond. The first decision node branches into two paths: a true (T) branch to the left and a false (F) branch to the right. The left branch leads to a second decision node. This decision node has a true branch leading to one process node and a false branch leading to a second process node. The two process nodes then merge into a single path. The right branch from the first decision node leads to a third decision node. This decision node has a true branch leading to one process node and a false branch leading to another process node. These two process nodes also merge into a single path. The merged paths from the left and right sections join together and continue downward to a fourth decision node near the bottom of the diagram. The bottom decision node branches into a true path leading to one process node and a false path leading to a second process node. These two process nodes then merge into a final path. Throughout the diagram, decision branches are labeled T for true and F for false. The diagram contains one initial decision, two intermediate decision nodes operating in separate branches, and one final decision node after the branches rejoin.
Trаde Pаtterns (15 pоints; 10 min.): (а) Hоw are the patterns оf international trade, that is the pattern of what different countries export and import, explained? (Please discuss at least three determinants of trade, at length).(b) Two basic models of international trade are the simple trade "openness" model and the gravity model. Please write the equations that represent both models, discuss what information they provide, and discuss how the models differ, and, importantly, what determinants of trade each might overlook. (Note: when writing equations, use numbers in place of subscripts, and be sure to use brackets or parentheses to group variables according to order of operation. For example, if I wanted to show the aggregate of GDP for Country 1 and GDP for Country 2, all divided by X, I would write the equation in the following way: [GDP1 + GDP2] / X, so that the reader would know that the GDPs must be added to each other before dividing by X).
