Article: Bags of Love
Last year, I worked in a middle school near my mother's house, and I stayed with her for a month. During that time, I helped her do some housework and buy some food.
After the first week, I noticed that the food was eaten up very quickly. Then I began keeping an eye on my mum. To my surprise, I found that she would put some of the food into a paper bag and go out with it at about nine every morning. And finally, I decided to follow her. I saw her taking the food to the street children. She would also spend a lot of time talking and playing with them.
One day, I talked to a neighbour and found out that my mum was well-known in the area. The children were very friendly with her and even thought of her as their own mother. Then it hit me - why wouldn't she want to tell me about it? Was she worried that I would stop buying food if I found out?
When my mum got home, I gave her a big hug  .I told her she didn't need to keep it a secret from me. And she told me something about the children. Some of them lived with an old lady in a small house. Others slept on the street. For years, she was helping the poor street children by giving them food. After she told me everything, I was so moved by how selfless   she was. She helped others in need. As her son, I was so proud of my mum.
I continued to buy food for my mum after that. But I always added one more bag for her other children.
Question: How did the writer feel about his mum after she told him everything?
Options: A: He was proud of her.
B: He was confident in her.
C: He was angry with her.
D: He was worried about her.
The question asks the reader to select an answer that reflects how the writer felt about his mother after she told him everything. Based on this, we first need to determine what "everything" refers to and whether or not it is related to any of the options.
In paragraph 4, when speaking with a neighbor, he finds out that his mom has been helping street children for years by giving them food. In paragraph 5, he talks about being moved by her selflessness and wanting her other son’s (himself) help continue providing food for those who are needy because they have no home and sleep on streets during cold days/nights without shelter.. He also mentions feeling proud of her in P6: I was so proud of my mum... As her son - I was so
John decided to buy 10 pins for himself.  They are normally $20 each but they were on sale for 15% off.  How much did he spend on pins?
The sell reduced the price of each pin by 20*.15=$<<20*.15=3>>3
So he paid 20-3=$<<20-3=17>>17 per pin
So the total cost was 17*10=$<<17*10=170>>170

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.
