answer:To make the most of your 3-week solo trip to Europe, I recommend starting by narrowing down your country options based on scenic landscapes and cultural experiences. Considering your budget and travel style, I suggest focusing on Central or Eastern Europe, where costs are relatively lower and there's a rich cultural heritage to explore. Given your preferences, a possible itinerary could include visiting Croatia, Slovenia, and Austria. Croatia offers stunning natural beauty, from the Dinaric Alps to the Adriatic coast, while Slovenia boasts picturesque mountains, forests, and a charming capital city, Ljubljana. Austria, meanwhile, is famous for its grand cities, opera houses, and museums. In May, the weather in these countries is mild, making it an ideal time to explore the outdoors. To pack lightly, consider visiting places with similar climates and activities, allowing you to reuse clothing items. Focus on layers, as mornings and evenings can be cool, especially in the mountains. To immerse yourself in local cultures, consider staying in smaller towns or cities, where you can easily interact with locals and experience authentic traditions. For example, you could stay in Plitvice, Croatia, to explore the stunning national park, or in Lake Bled, Slovenia, to enjoy the serene lake surroundings. Budget-wise, allocate approximately 1,500 for transportation, including flights, buses, and trains. Accommodation costs can vary, but budget-friendly options like hostels or Airbnb apartments should cost around 30-50 per night. Food and activities can be managed within 30-50 per day, leaving some room for splurging on unique experiences. In terms of itinerary, consider spending around 7-10 days in each country, allowing you to explore different regions without feeling rushed. Leave some room for spontaneity and flexibility, as you may discover hidden gems or want to linger in certain places. Next, I can help you create a more detailed itinerary or discuss specific destinations within these countries. What would you like to focus on next?

answer:Renting a car can be a great idea for exploring Croatia, Slovenia, and Austria, as it provides flexibility and allows you to reach more remote areas. However, it's essential to consider the following factors before making a decision: Pros of renting a car: * Flexibility to create your own itinerary and make spontaneous stops * Ability to explore rural areas and national parks * Scenic drives through stunning landscapes Cons of renting a car: * Additional costs for fuel, tolls, and parking * Potential difficulties with navigation and language barriers * Parking challenges in urban areas Factors to consider when renting a car in these countries: 1. **Border crossings:** Make sure the rental company allows border crossings into neighboring countries. Some companies may have restrictions or additional fees. 2. **Insurance:** Check if the rental company offers comprehensive insurance that covers you in all three countries. Consider purchasing additional insurance for peace of mind. 3. **Fuel costs:** Fuel prices can vary between countries.

Public transportation is generally efficient and convenient in these countries, so you may not need a car for the entire trip. Next, I can help you explore public transportation options or provide more information on driving in these countries. What would you like to focus on next?

answer:For each of the 4 goalies who stand in the net, there are (25 - 1 = 24) other players, which include the remaining 3 goalies, who will take penalty kicks against them. Therefore, the total number of penalty kicks for each goalie standing in the net is 24. The total number of penalty kicks is then 4 times 24 = boxed{96}.
