I'm taking a test and have to guess the right answer to the question after the article.
Article: Mattie Stepanek died at the age of 13 from a rare disease called muscular dystrophy. Because of the disease, Mattie had to get around in a wheelchair, but it did not stop him from staying positive and inspiring others with his message of peace. As a best-selling author and role model, Mattie provided a voice for people who suffer from muscular dystrophy. He spoke to people about the disease and about his dream for world peace. 
"Mattie was something special, something very special," said Jerry Lewis, the chair of the Muscular Dystrophy Association, a group that works to find a solution to the disease. "He was an example that made people want to reach for the best within themselves." 
Mattie moved many people through his speeches and interviews, but he may have touched the most people through his poetry. During his life, Mattie wrote five books of poetry. Three of those books were The New York Times best-sellers. His books all had the word "Heartsongs" in the title. Mattie called his inner voice that encouraged him to work for peace his "Heartsongs". 
When his first book came out, just 200 copies were printed to be handed out to friends and supporters. But after the news of the book spread, 500,000 more copies were printed. People think Mattie's poems are very thoughtful. 
Mattie first started writing poetry at the age of 3 to help him face the death of his brother, who also suffered from muscular dystrophy. 
The magazine Time For Kids once interviewed Mattie. He told the reporter, "Life is a gift. We have to make the best of it." Mattie said his task was to bring peace to the world.
Question: The dream of Mattie Stepanek was to   _  .
Options: A: become a famous writer
B: find a cure, for the disease
C: work for world peace
D: save his brother
The text mentions that Mattie became known as a best-selling author and role model. It says, "He spoke to people about the disease he had and his dream for world peace." This shows that Mattie wanted there to be peace in the world -- not just between countries but also among all types of different people who have differences from one another.
Option D does not make sense because it seems like option C is more likely than saving his brother (which was mentioned later on in the article). Option A might seem correct at first glance, but remember what we read earlier: 
"Mattie moved many people through his speeches and interviews..." Even though this sentence refers back to something else written before in the article (his book), it still has some details which hint at why Option
Nadia walked 18 kilometers, which was twice as far as Hannah walked. How many kilometers did the two girls walk in total?
Hannah = (1/2) 18 = 9
9 + 18 = <<9+18=27>>27 km
Together they walked 27 kilometers.

You are an expert at transforming general questions into domain-specific, math-related questions. Your task is to generate only the transformed math question without including any answers or solutions.

### Step-by-Step Instructions
#### Step 1: Analyze and Understand the General Question
   - Objective: Fully understand the general question to grasp its context, key concepts, and quantitative elements.
   - Guidelines:
     - Identify the core topic (e.g., measurement, comparison, probability) and **specific details** that can inspire mathematical transformations.
     - Consider how the question’s **structure and format** might be adapted to a mathematical context. For example, if the question compares quantities or discusses measurements, consider framing these as math problems involving calculations, rates, or proportions.

#### Step 2: Refer to the Domain-Specific Question (for Inspiration Only)
   - Objective: Use the domain-specific question to understand how similar questions are formulated in a mathematical way.
   - Guidelines:
     - Extract Core Concepts: Identify the main mathematical ideas in the domain-specific question and consider how these concepts can apply to the general question.
     - Focus on Transformation, Not Duplication: Use the structure of the domain-specific question as a guide but create a unique question aligned with the general question’s theme.
     - Frame questions to encourage mathematical reasoning, such as using multi-step calculations, logical problem-solving, or real-world applications.

#### Step 3: Generate the Transformed Math Question
   - Objective: Create an original math question that retains the context and theme of the general question pair.
   - Guidelines:
     - Preserve Original Context: Integrate elements from the general question (e.g., scenario, characters, or objects) into the math question to make it cohesive and relevant.
     - Introduce a Mathematical Challenge: Frame the question to require mathematical thinking, such as:
       - Calculations (e.g., “Calculate the time needed if…”)
       - Comparative reasoning (e.g., “Determine which option has a higher value if…”)
       - Probability or logic-based reasoning (e.g., “What are the chances of selecting a specific item if…”)
     - Avoid Including Solutions: Ensure the output contains only the transformed math question without any answers or calculations.

### Response Rule
- Generate **only the "Transformed Domain Question"** for **Example 4** without including any answer, explanation, or solution.

### Output Format
- **Transformed Domain Question**: [Write your transformed question here.]

### Example 1:
- **General Question**: Given the sentence "A man with a beard playing an instrument," is it true that "The person has a beard"?
- **Domain Question**: What is the total cost of purchasing equipment for all sixteen players on the football team, considering that each player requires a $25 jersey, a $15.20 pair of shorts, and a pair of socks priced at $6.80?
- **Transformed Domain Question**: In a concert audience of 1,000 people, where 45% of attendees are male and 30% of the males have beards, what is the probability of randomly selecting a bearded man from the crowd?

### Example 2:
- **General Question**: Acids have pH values below 7. The lower the pH value, the more strongly acidic the substance. Having read the above passage, choose the right answer to the following question (choices are higher or lower): You can find tables that show the pH value of different fruits and vegetables. The fruits such as apples are barely acidic so they have a pH value that is higher or lower?
- **Domain Question**: If Williams has a certain amount of money, Jackson has 5 times that amount. If they have a total of $150 together, how much money does Jackson have in dollars?
- **Transformed Domain Question**: In a study of soil pH levels across various agricultural zones, it's noted that some zones are more acidic due to the types of crops grown there. If Zone A has an average soil pH of 5.7 and is noted for its apple orchards, which are known for requiring slightly acidic soil, calculate the comparative pH difference percentage between Zone A and Zone B, where Zone B has a soil pH of 6.8, suitable for less acidic crop requirements.

### Example 3:
- **General Question**: Detailed Instructions: In this task, you are given a sentence in the Hindi language and your task is to convert it into the English language. In translation, keep numbers as it is and make it sentence case (capitalize only the first word of each sentence and noun).
- **Domain Question**: Mary and Ann are going sledding. Mary slides down a hill that's 630 feet long at a speed of 90 feet/minute. Ann slides down a hill that's 800 feet long at a rate of x feet/minute. How much longer does Ann's trip take than Mary? If we know the answer to the above question is 13, what is the value of unknown variable x?
- **Transformed Domain Question**: Given the geopolitical tension in the region described, if the fall of the Ottoman and Russian empires led to the redistribution of their controlled territories among other nations, assume these territories were divided into 10 new countries with varying sizes. The largest new country occupies 30% of the total territory once held by these empires. If the total land previously controlled by the Ottoman and Russian empires was 2,000,000 square kilometers, calculate the area of the largest new country in square kilometers.
