Describe the difference in execution between codes A and B. Code A if x > 80 end Code B if x > 80 elseif x > 70 60 70 end if x > 60 end ----- Consider X = rand(1,5). Explain why the syntax X([1 0 1 1 0]) does not provide the 1st, 3rd and 4th values of x. Also, provide the syntax required to extract the 1st, 3rd and 4th values of x using a logical. B I U X2 x? ABC 123 C Decreasing the step size increases the accuracy of the solution when solving an ordinary differential equation using Euler's method, Heun's method or the midpoint method. Provide two potential reasons for why realmin() isn't used as the step size when solving an ordinary differential equation. B I U X2 x EE ABC
