Student Testimony
I was completely overwhelmed with my APs at first. I didn’t have the motivation to study or the right resources to succeed. But Stellar changed everything.

“In the late 19th and early 20th centuries, American foreign policy was primarily defined by the pursuit of expansionism, driven by a belief in American exceptionalism and a duty to spread democracy and capitalism around the globe. This era saw the United States engage in several conflicts and interventions, including the Spanish-American War of 1898, which not only resulted in territorial acquisitions like Puerto Rico and the Philippines but also marked a significant shift in the nation's identity as a global power. This aggressive foreign policy was justified by arguments of moral obligation, presenting the annexation of overseas territories as a benevolent act aimed at uplifting less fortunate nations, thus embodying a humanitarian facade coupled with economic interests.”
Source: John A. Thompson, historian, “The United States and the Age of Imperialism”, 2003
“Contrarily, the rise of American imperialism during this period can be seen as a hypocritical endeavor, masking underlying motives of economic exploitation and nationalistic fervor under the guise of moral superiority. Critics of this foreign policy argued that instead of liberating oppressed peoples, the United States sought to reproduce its own dominance in foreign lands for the benefit of American corporations and investors. The consequences of such policies were often detrimental, leading to unrest and resistance in the territories affected, as exemplified by the Philippine-American War, where the rhetoric of liberation was starkly at odds with the reality of subjugation and violence. This imperialistic approach not only contradicted the founding principles of liberty and self-determination but also illuminated the darker side of America's global ambitions, showing that the nation's self-image was often built on the subjugation of others.”
Source: David S. Mason, historian, “Imperialism and American Identity”, 2010
Using the excerpts, respond to parts a, b, and c.
a. Briefly describe one major difference between Thompson’s and Mason’s interpretations of American foreign policy in the late 19th and early 20th centuries.
b. Briefly explain how one historical event or development from 1865 to 1917 not directly mentioned in the excerpts could be used to support Thompson’s interpretation.
c. Briefly explain how one historical event or development from 1865 to 1917 not directly mentioned in the excerpts could be used to support Mason’s interpretation.

The temperature of a lake is modeled by a continuous and differentiable function, T(t), which measures the temperature in degrees Celsius at time t (in hours). The following table displays selected values of T(t) over a period of 8 hours.
| t (hours) | 0 | 1 | 3 | 5 | 8 |
|---|---|---|---|---|---|
| T(t) (°C) | 15 | 17 | 20 | 23 | 25 |
(a) Using a right Riemann sum with the intervals [0, 1], [1, 3], [3, 5], and [5, 8], approximate the value of the integral
(b) According to the Mean Value Theorem for Integrals, must there exist a time c in [0, 8] such that T'(c) equals the average value of T over that interval? Justify your answer.
(c) Using the average temperature calculated in part (a), estimate the total increase in temperature from t = 0 to t = 8. Provide the mathematical setup for your calculations.
(d) When the temperature of the lake is 25°C, the rate of change of the temperature is given by

This question involves the TemperatureRecord class, which records daily temperatures for a week. You will write two methods in the TemperatureRecord class that help analyze the temperature data.
(a) Write the calculateAverageTemperature method, which calculates the average temperature for the week. The method should add up all the temperatures in the dailyTemperatures array and divide by the number of days (7). If the sum is 0, due to initialization conditions, ensure it returns 0 as the average.
Class information for this question
(b) Write the countDaysAboveThreshold method. This method iterates through the dailyTemperatures array and counts how many days have temperatures above the provided threshold. The count is then returned.
Consider the following examples:
| Input Temperatures | Threshold | Output |
|---|---|---|
| [70, 75, 80, 85, 90, 95, 100] | 80 | 4 |
| [60, 65, 70, 75, 80, 85, 90] | 80 | 3 |
| [0, -5, -10, -15, -20, -25, -30] | -10 | 2 |
Each input will be a valid set of 7 daily temperatures.
Complete the countDaysAboveThreshold method, ensuring that it iterates correctly through the dailyTemperatures array.

In a 2021 TED Talk, renowned author and philosopher Alain de Botton stated: "Our culture has created the illusion that the arrived-at life is a happy life. We believe that all we need to do is find our dream job, buy a house, or travel to exotic places, and we will be fulfilled. Yet true contentment comes from a deeper understanding of ourselves, our relationships, and the acceptance of life’s inherent challenges and uncertainties."
Write an essay that argues your position on the extent to which de Botton's claim about the pursuit of happiness and fulfillment is valid.
In your response you should do the following:
