Have you ever been to the world's smallest bookstore?
The World's Smallest Bookstore,whose official name is just these three words,sits quietly about 100 miles northeast of Toronto.
The bookstore is about 10 feet by 10 feet,so it is easy to imagine how tiny it really is.The bookstore is open 24 hours a day.Inside the bookstore are various books,especially literary books and classic authors' works.So if you are looking for something less popular,you may get a bit disappointed there.
Another special feature of this bookstore is that each book only costs three dollars.All the expenses are paid on the honor system,which means buyers should make a note of what they've bought and leave their money by themselves.So the tools of the trade in this bookstore are quite simple: pens,papers,light bulbs and a label-maker.
In order to catch passers-by's attention,the billboards of the bookstore are several times bigger than the store itself.With these large eye-catchers,many people are willing to stop by and have a visit.
What's the passage mainly about?
A) The world's smallest bookstore.
B) A strange way of selling books.
C) The popular books nowadays.
D) The popular bookstores in the world.
The article is mainly about the world's smallest bookstore. It gives a detailed description of this unique place, including its physical size and location, hours of operation, book selection, cost structure. The author also describes how to attract visitors by using billboards that are much larger than the store itself.
So A is correct answer
A yearly book sale is held in school where students can sell their old books at a cheaper price. Two-fifths of Lovely's books can be sold for $2.50 each and the rest for $2 each. How much will Lovely earn if all 10 books were sold?
Lovely will sell 10 x 2/5 = <<10*2/5=4>>4 books for $2.50 each.
She will sell 10 - 4 = <<10-4=6>>6 books for $2 each.
Her earnings for the 4 books at $2.50 will be $2.50 x 4 = $<<2.5*4=10>>10.
Her earnings for the 6 books for $2 each will be $2 x 6 = $<<2*6=12>>12.
Thus, Lovely's total earning if all 10 books are sold is $10 + $12 = $22.

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.
