I'm taking a test and have to guess the right answer to the question after the article.
Article: Venice is the "Queen" of the Adriatic Sea  . Every year thousands of people from all over the world travel to Italy to visit the city. Do you know why they like to go there for a visit?
Venice is a very beautiful city. It is quite different from other cities in the world. There aren't any roads and streets in the city. So there aren't any cars and buses. There are many canals in the city. There is one big canal and one hundred and seventy-seven small canals. People move up and down the canals in boats to go to work, go shopping or visit their friends.
But Venice is sinking. It is going down and the water is going up. In 2040Venice will be under water, The Adriatic Sea will cover the city. The Venetians  love their city and want to stay there. So they want to save Venice? They can build some strong huge walls and gates in the sea. The gates will close to keep too much water out. Thus Venice will not sink.
Question: The Venetians usually go to work or visit their friends  _  .
Options: A: by bus.
B: by bike.
C: in cars.
D: in boats.
The article says that Venetians use boats to get around. There are no cars or buses in the city and it is surrounded by water, so people must travel from place to place via boat. The answer is D, "in boats.
Without factoring in the cost of depreciation for his car John made $30,000 doing Uber.  When he finally traded in the car he bought for $18,000 he got $6000 back.  What was his profit from driving Uber?
His car depreciated 18000-6000=$<<18000-6000=12000>>12000
So he made a profit of 30000-12000=$<<30000-12000=18000>>18000

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.
