Где находится Российская Федерация? Какую часть земной поверхности занимает Российская Федерация? Какова общая площадь страны? Какие моря и океаны страна омывается? С какими странами граничит Россия? Каков климат в России? Какие горные цепи есть в России? Какая горная цепь отделяет Россию от Азии? Сколько рек в России? Россия богата лесами, не так ли? Чем богата Россия полезных ископаемых? С какими странами. Что такое столица России? Является ли Россия парламентской республикой? Кто правит страной? Какова сейчас политическая и экономическая ситуация в стране.

Ну, вроде так. =)
Inventions of the future that must already exist
We live in the world of technology. Yesterday's future is rapidly becoming the past for us. Engineering and technology are changing at an incredible pace, appearing and soon becoming obsolete.
Now many ideas of science fiction novels came true. Let’s take a look at the inventions of the future, which should have already appeared or are going to appear very soon.
1. Time machine
Theoretically, the idea of the time machine is well described, but its practical implementation is not yet available. Moreover, the main question is not the fact of travel, the ability to see the events of the distant past or possible future, but the theory of time, its linearity or multivariance...
2. Antigravity
Antigravity could have a significant impact on the transport system and construction technology. Even humankind could change. Indeed, lack of weight greatly affected appearance and physiology of an organism. Although on the other hand, have you really never wanted to flutter like a butterfly, without experiencing load, without feeling your own weight!
3. Holograms
We are close to appearance of holographic images. There are already 3D technologies that are becoming more affordable and widespread. Although so far these are just some visual effects, we still have a long way to go to fully simulate reality using holograms.
4. Food vending machines
There are infinitely many variants of this invention. But the main point is that you can get almost any substance with set parameters. How exactly a vending machine works - transforming one substance into another, or synthesizing something from nothing - is not important. Some restrictions on the use of technology are also expected, but in general the idea is very interesting, especially in terms of the growing global population and the food problem.
5. Laser weapons
Science fiction has produced an infinite number of types and kinds of laser weapons. They can be in the form of lightsabers or laser guns that spew a beam of coherent light. A powerful weapon the main problem of which is energy consumption. And by the way its prototypes have already long existed
6. Androids
Robotics is already quite advanced. Robots are becoming more complex and smaller in size. They can perform quite complex functions, master human professions and emotions. But so far they are not capable of full communication, although significant progress has been made in the field of artificial intelligence.
7. Teleportation
Teleportation is everyone's dream. This technology is especially important for everyone who waste time in traffic jams, gets late for a meeting, even for those who find it so hard to get away from the computer and go to bed. Teleportation would make our lives more exciting, cities cleaner. It would solve problems of transport, fuel, clean environment.
8. Invisibility
Invisibility in everyday life would be a big problem. Although it would be rather a socio-psychological problem. But for military purposes, invisibility is being actively developed as perfect camouflage. There is already invisibility technology in certain wave spectra, such as "stealth technology", and invisibility cloaks with very good results have also been developed.
9. Flying cars
This invention is almost here. Until now, flying cars were created only as experimental models, but the first flying car for mass production and sale has already been certified in the USA!
10. Jet engine suits
In general, jet engines are developed quite well at the moment. But there is a problem of their energy efficiency and controllability. There are jetpacks, but they are still used as expensive toys only.
