a. Trapezoid rule
b. Simpson's rule
c. Euler's method
d. Fourier transform

Answer 1

1. The Glycemic Index measures the relative rise in blood glucose levels (Option B).

2. The Glycemic Index of a food item typically calculated using an AUC (area under the curve) glucose/blood graph is Trapezoid rule (Option A).

Step-by-step explanation:

The Glycemic Index measures the relative rise in blood glucose levels after eating food. Calculating the Glycemic Index of a food item typically involves comparing the blood glucose response curve of the test food with that of a reference food such as pure glucose. The area under the curve (AUC) is used, which represents the total increase in blood glucose levels after consuming the food.

The most common method to calculate AUC is the trapezoid rule, which approximates the area under the curve by summing the areas of a series of trapezoids beneath the curve. Each trapezoid's area is calculated using the recorded blood glucose levels at various time intervals after food consumption.

Thus, the correct answer is

1. B.

2. A.
