A patient sustained a hand injury during a fall and now presents with significant edema in the fingers and dorsum of the hand. Which of the following methods is considered the gold standard for quantifying this edema in comparison with the uninvolved extremity?

Bonus Question 1 (5 points) Counterfactual Scenario (for educational purposes): Ref: WSJ Suppose that on September 17, 2025, the Federal Reserve decreases the federal funds rate by 0.25 percentage points. Imagine that, in this hypothetical scenario, mortgage rates are also expected to decrease. A fall in mortgage rates lowers the cost of borrowing, making housing more affordable to consumers. From the perspective of demand theory, the demand curve for the housing market will (1)____________ (increase or decrease; 1 point). Now suppose that, at the same time, tariffs are imposed on imported construction materials. As a result, the prices of key inputs such as steel, lumber, and cement increase, raising the overall cost of constructing new homes. From the perspective of supply side, the supply curve for the housing market will (2)____________ (increase or decrease; 1 point). In this counterfactual setting, we expect the equilibrium price of houses to (3)_______________ (increase or decrease; 3 points). However, the equilibrium quantity of houses could either increase or decrease depending on the relative magnitudes of the demand shift (from cheaper financing) and the supply shift (from higher construction costs). Write your answers: (1)____________[1 point] (2)____________[1 point] (3)____________[3 points]

A trader opens a long position in NVDA at a bid price of $500, using $1,000 of their own capital and 50% margin. If, one year later, the price of NVDA is $475, what is the trader’s net payoff per dollar of capital? Assume the margin loan does not require interest.

Challenge You’re a derivatives trader, and your college friend Jordan tells you about a hedge fund they’re starting. Jordan promises a “[R0] percent per year return.” The fund has a [T]-year “lock-up,” meaning you must invest immediately and will receive your return in one lump sum at the end of [T] years. You invest $[PV], but then begin second-guessing yourself. As a derivatives trader, you assumed your friend meant continuous compounding, but they may have meant annual discrete compounding instead. How much less will you receive at the end of the lock-up if Jordan’s promised return was actually discrete rather than continuous? (Hint: your answer should be a positive number.) Enter your answer as a number of dollars, rounded to the nearest whole dollar. For $12,345.67, enter 12346.

A one-year Treasury bond pays a $2 coupon in six months and $102 in one year (including the $100 face value and final coupon). The bond’s current market price is $100.25. A six-month T-strip with a $2 face value has a 4.00% annual yield, continuously compounded. A one-year T-strip with a $102 face value has a 4.50% annual yield, also continuously compounded. Using a T-strip replication portfolio strategy, what arbitrage profits can a trader earn?
