There are several reasons why no modern cities are being built in Europe. One reason is that much of Europe is already densely populated, making it difficult to find large enough areas of undeveloped land for new city construction. Additionally, there are strict regulations and zoning laws in place that make it challenging to obtain the necessary permits and approvals for large-scale urban development projects. Furthermore, the high cost of land and construction in Europe makes it financially prohibitive to build entirely new cities from scratch. Finally, many European countries are focusing on urban renewal and redevelopment of existing cities rather than creating entirely new ones. **

Yes, a smart carpet with telephone function can be built using modern technology. The carpet could be embedded with sensors and microphones to detect footsteps and voices, and then connect to a smartphone or a central system to make and receive calls. Additionally, the carpet could be integrated with voice recognition technology to accurately pick up and process spoken commands. With the advancement of smart home technology, it is feasible to create a carpet that can also function as a telephone. **

With modern construction methods and technology, Cologne Cathedral could potentially be built much faster than it was originally constructed in the medieval era. The use of advanced machinery, materials, and construction techniques could significantly speed up the building process. It is difficult to provide an exact timeline, but it is likely that Cologne Cathedral could be completed in a fraction of the time it took to build it originally, which was over 600 years. **

Built-in appliances are designed to be integrated into cabinetry or a wall, offering a seamless and custom look. Built-under appliances are similar to built-in, but are designed to fit underneath a countertop. Freestanding appliances are stand-alone units that can be placed anywhere in the kitchen without the need for installation within cabinetry or walls. Each type of appliance offers different design and installation options to suit the specific needs and layout of a kitchen. **

Tunnels are built for a variety of reasons, including providing transportation routes through mountains or bodies of water, creating underground pathways for utilities such as water, sewage, or power lines, and for mining and exploration purposes. Tunnels can also be built for military and defense purposes, such as creating underground bunkers or secret passages. Additionally, tunnels can be constructed for environmental reasons, such as creating wildlife crossings to help animals safely navigate through human infrastructure. **

As an AI language model, I don't have the ability to physically observe or assess your body. However, if you have been consistently engaging in strength training exercises and have been progressively increasing the intensity of your workouts, it is likely that you have built muscles. It's important to track your progress through measurements, strength gains, and changes in your body composition to determine if you have indeed built muscles. If you have been following a structured workout program and have been fueling your body with adequate nutrition, it's possible that you have seen muscle growth. **
