3.3 What’s suggested by Bland to avoid the cycling in primal Simplex? (a) Use the minimum-element rule to select an entering variable and break the tie arbitrarily; (b) Use the minimum ratio rule to select a leaving variable and break the tie arbitrarily; (c) Use the least index rule to select an entering variable with a negative coefficient in the z-row; (d) Use the least index rule to break the tie in the selection of a leaving variable (based on the minimum ratio rule).

A population of wild sunflowers (Helianthus annuus) inhabits a drought-prone habitat. Jane is a scientist interested in understanding the evolutionary dynamics of this system, and has recorded data on this population for multiple years at the end of each growing season. Below is part of her dataset. Year 2012 2013 2014 2015 2016 2017 Population size (# individuals) 152 147 31 78 125 145 Mean plant height (cm) 215 230 105 195 205 217 Mean leaf size (cm²) 20.2 18.6 5.1 5.7 5.9 5.4 Mean number of branches (#) 4.1 4.0 4.2 3.9 4.2 4.1 Mean seed production (# seeds/plant) 25 28 5 26 24 27 The year 2014 was a severe drought year for this population, while all other years have been relatively moist. Jane sees patterns in her data, and knows from other sources that some of her traits are highly heritable and others are not. While this heritability data is not presented, based on the change in mean trait values over time in Jane's dataset, which scenario is compatible with the data? Mean number of branches is not heritable but highly plastic with environment. Mean number of branches is both heritable and highly plastic with environment. Mean plant height is not heritable and responded to selection from the drought event. Mean leaf size is heritable and responded to selection from the drought event.

2. (22 pts) Function with matrix argument: Programming Exercise 8.1 on page 326 (prompt user to enter the elements in a matrix and call a function to find the sum of each column). • Include a printout of the main program and the function. • Include printouts for the test case in the textbook as well as one additional test case. Sections 8.2-8.5 *8.1 (Sum elements column by columns) Write a function that returns the sum of all the elements in a specified column in a matrix using the following header: const int SIZE = 4; double sumColumn(const double m [] [SIZE], int rowSize, int columnIndex); Write a test program that reads a 3-by-4 matrix and displays the sum of each col- umn. Here is a sample run: Enter a 3-by-4 matrix row by row: 1.5 2 3 4 Enter 5.5 6 7 8 Enter 9.5 1 3 1 Enter Sum of the elements at column 0 is 16.5 Sum of the elements at column 1 is 9 Sum of the elements at column 2 is 13 Sum of the elements at column 3 is 13
