Read the following article and answer the question.
Article: Dave needed to prepare for Saturday's fishing trip. He went into his hall closet, where he had more than 20 rods and reels. Nowadays he went fishing twice a year at Big Bear, a huge lake in southern prefix = st1 /Californiaabout 7,000 feet up in the mountains.
California tries to improve the fishing industry by sponsoring a Free Fishing Day twice a ear, once in June and once in September. That's enough for Dave. He went mostly because it was a social event with a few friends, not so much to catch fish. Even driving up a twisty two-lane road was worth the trip. Let alone the big, beautiful houses and trees that lined the shore of the lake.
Preparing was a project in itself. Dace had even created a computer file named Fishing Trip. It was a checklist of 45 things to take to Big Bear. He took two rods, because on Free Fishing Day you were allowed to fish with two rods instead of the usual one rod. He took a sweatshirt, jeans, two pairs of socks, a heavy hooded jacket, winter gloves, and a scarf. He also took flip-flops, shorts, a T-shirt, sunglasses, a big hat, and lightweight raincoat. If you go to Big Bear in June, you'd better be prepared for hot or cold, rain or shine.
He prepared a couple of magazines to read just in case the fish weren't biting. He and his friends joked that the fish were always biting- in the spot you just left or the spot you were headed for.
After about an hour and a half; Dave had gathered all the items on his list into a neat pile next to his door. He went to bed knowing that tomorrow's weather and fishing were unpredictable, but the good time with his friends was a given.
Question: Dave went go Big Bear twice a year mainly to_.
Answer:
The context of the article is that Dave needs to prepare for his annual fishing trip and has organized a checklist on his computer. 
Dave mentions he goes mostly because it's a social event with friends, not so much to catch fish. This implies that meeting up with friends is one of the reasons why he goes on this trip twice a year.
Based on this, we can conclude that "meet his friends" was an important reason as to why Dave went go Big Bear twice each year.


So meet his friend are the answer
Barbara went shopping in a supermarket. She bought 5 packs of tuna for $2 each and 4 bottles of water for $1.5 each. In total, she paid $56 for her shopping. How much did Barbara spend on different than the mentioned goods?
For the tuna Barbara needed to pay 5 * 2 = $<<5*2=10>>10.
For the four bottles of water, she needed to pay 4 * 1.5 = $<<4*1.5=6>>6.
On different goods Barbara spend 56 - 10 - 6 = $<<56-10-6=40>>40.

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.
