I'm taking a test and have to guess the right answer to the question after the article.
Article: When a friend calls out "Wait a second, I have a trick to show you," don't you always stop and wait? Tricks are hard to resist. No one is ever too old to enjoy them or too young either. In fact, many of the most successful tricks are really quite simple. They don't require special equipments or hours of practice. For example, you tell a friend "Pick a card", then you surprise him by telling him which card he picked. Here's how it is done. Take a pack of cards and secretly look at the bottom card. Put the cards facedown on a table, and ask your friend to pick a card. Then place the card at the bottom. 
Has your friend picked the cards by taking part of the cards from the top and putting it at the bottom? Start turning the cards up one at a time. You can pretend to think hard about each card. Look for the bottom card at the beginning which you have remembered. The cards that come after it will be the one your friend picked. Also, a mind-reading trick is fun to do at a party. You leave the room, and while you are gone, a tea cup is placed upside down over a penny, nickel($0. 05), dime($0. 1)or quarter($0. 25). When you come back into the room, you can tell which coin the tea cup is hiding. To do this trick, you only need a helper, or partner. Before hand, you two work out some signals. If he looks up. it's a penny; if he looks right, a nickel. You see, they are all very easy. Why not have a try?
Question: The author's main purpose to write this passage is  _  .
Options: A: to tell the readers tricks are done to fool people
B: to give the readers knowledge about all kinds of tricks
C: to tell the readers how to do some easy tricks to enjoy themselves
D: to say tricks are very popular
The author wrote this article to give the readers knowledge about tricks and how they are done. The passage is written in a way that would be interesting for someone who wants to learn more about magic and illusions without having any prior experience with these topics. It also includes specific instructions on "how" to do some easy tricks, which further demonstrates that C is most likely the correct answer choice
Karen has 32 quarters in her piggy bank.  Her older brother Christopher has 64 quarters in his piggy bank.  How much more money does Christopher have?
Christopher has 64 quarters so he has 64*.25 = $<<64*.25=16.00>>16.00
Karen has 32 quarters so she has 32*.25 = $<<32*.25=8.00>>8.00
If Christopher has $16.00 and Karen has $8.00 then Christopher has 16-8 = $<<16-8=8.00>>8.00 more than Karen

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.
