### Understanding Utility, Preferences, and Substitution Effects

#### Problem 1
**Thomas has utility \( U = \min\{3C, T\} \) over cookies and tea. Suppose the price of cookies declines by 1 dollar. How much of the change in demand for tea is a substitution effect? In other words, what is \( \frac{\text{change in } h_T}{\text{change in } g_T} \)?**

- a. 0
- b. 1/4
- c. 1/3
- d. 2/3
- e. 3/4
- f. 1

*Selection:* a. 0

#### Problem 2
**Which of the following utility functions does NOT represent the same preferences as \( U(x, y) = x^{1/2} y^{1/2} \)?**

- a. \( U(x, y) = xy \)
- b. \( U(x, y) = \ln(x) + \ln(y) \)
- c. \( U(x, y) = \ln(x \cdot y) \)
- d. \( U(x, y) = x^{1/2} + y^{1/2} \)

*Selection:* d. \( U(x, y) = x^{1/2} + y^{1/2} \)

### Detailed Explanation:
In Problem 1, Thomas's utility function \( U = \min\{3C, T\} \) implies that Thomas's satisfaction depends on the lesser or limiting factor of \( 3C \) (three times the quantity of cookies) or \( T \) (the quantity of tea). When the price of cookies decreases, typically a substitution effect may be observed if the relative consumption of goods changes due to a price change. In this case, the substitution effect in question results in no change in the demand for tea, thus the ratio is \( \frac{\text{change in } h_T}{\text{change in } g_T} \) = 0.

In Problem 2, four different utility functions are given, and the task is to identify which one does not represent the same preferences as \( U(x,y) = x^{1/2} y^{1/2} \). The function representing the product of \( x \) and \( y \) with
