1. The phrase Darwin used to describe his broad theory of evolution is "descent with 2. All of life is related through common ancestry, accounting for the of life. 3. The of life arises from the adaptation of species to different habitats over long spans of time. 4. Darwin proposed a mechanism for how evolution occurs, which he called 5. Two key observations underlying natural selection are that members of a population vary in their and that all species can produce more offspring than the environment can support. 6. Darwin inferred that those organisms with traits best suited to the environment tend to leave more than other members of a population. 7. This unequal reproduction in a population leads to the gradual accumulation of to the environment.

Indicate the following system parameters and behavior.\ a) What is the system's order, n, input and output?\b) Find any eigenvalues \lambda_n associated with the system.\ c) Is the system stable or unstable? Give your reasoning.\ d) Is the system overdamped, critically damped or under damped? Give your reasoning.\ e) Find the system's time domain behavior for f(t) = 0 (i.e. zero-input) with y(0) = 1\ and \dot{y}(0) = 2 via the solution y(t).

You have been stopped on State Street on your way to lunch by an evil sorcerer. He knows you have enough money to get 4 slices of pizza and 2 sodas given the prices the restaurant currently charges, and he knows that this combination would have given you 100 units of happiness. "Muhahah" he says. "You have two choices: 1. I can make the restaurant change the price of pizza so that by the time you get there your budget constraint has changed or 2. I can make some of the money in your pocket disappear even though the prices are the same. Either way your new utility will be only 75 utils!!! He cackles wildly while you make your choice. If you choose option 2, what changes in your optimization graph, and what can that be used to show? Your budget constraint would shift in by the amount he stole from your pocket, which could show the substitution effect. The new budget constraint would have the same slope as your old budget constraint. Your budget constraint would shift in by the amount he stole from your pocket, which could show the income effect. The new budget constraint would have a different slope from your old budget constraint.
