An economy can produce good 1 using labor and capital and good 2 using labor and land. The total supply of labor is 100 units. Given the supply of capital, the outputs of the two goods depend on labor input as follows:The marginal product of labor curves corresponding to the production functions are as follows:a. Suppose that the price of good 2 relative to that of good 1 is 2. Determine graphically the wage rate and the allocation of labor between the two sectors. b. Using the graph drawn, determine the output of each sector. Then confirm graphically that the slope of the production possibility frontier at that point equals the relative price. c. Find the effects of the price change from 2 to 1.3 on the income of the specific factors in sectors 1 and 2.

This task designs a simple access control system including 4 buttons and 1 7-segment display driver. The basic functions are as follows: 4 buttons, respectively representing the numbers 0,1,2.3 The password is set in advance in the program, with the number between 0 and 3 The 7-segment tube displays "-", indicating waiting for password input When the password is entered correctly, the character "P" is displayed about 3s, and the lock is opened through P3.0; Otherwise, the character "E" is displayed, about 3s, and the lock remains locked.

Read the text and decide the function of the 1st sentence in the text. Managers will often put a CV on the rejection pile for any number of reasons. This is not something one should take personally. It happens because they will receive hundreds of applications for a job and need a way to cut that number down quickly to the twenty or so they intend to interview. The list is obviously endless, but includes major gaps, such as lack of qualifications, and minor oversights, such as spelling errors. What is the function of the 1st sentence in the text?

A、supporting reason

B、topic sentence

C、example

D、summary
