From the following options presented in the problem, the only global city in the region of Russia and its neighboring countries would be A. Moscow.
Of the options presented, between Moscow, Kiev, St. Petersburg, and Tashkent, the only global city would be Moscow. Kiev and Tashkent aren't located in Russia. This leaves Moscow and St. Petersburg. Although some would argue that St. Petersburg would be the answer, it is a fact that St. Petersburg is yet to be called as a global city. Moscow, on the other hand, is already declared one though its activities as one is limited. Both are solely affected as to Russia's approach in the overall development of the country and is yet to show progress.

Explanation:
Transit Photometry is the most widely-used and effective to date, it has been a method that measures the light curve of distant stars for periodic dips in brightness. These are the result of exoplanets passing or transiting in front of the star relative to the observer. It is currently the most effective and sensitive method for detecting extrasolar planets, particularly from an observatory in space. When combined with radial velocity data, a transit can also provide a good estimate of the planet's mass. This method detects distant planets by measuring the minute dimming of a star as an orbiting planet passes between it and the Earth.
The main reason direct detection of exoplanets is difficult is because most planets orbit planets orbit at small angular separations on the sky, this means a direct detection is only possible if the star's light can be suppressed or occulted such that the faint light from the planet can be detected.
Some planets are found via the wobble method, using both methods, combining mass and size, scientists can calculate the planet's density, an important step towards assessing its composition.
If we observe the light from space is exhibiting a red shift.This would mean the universe is expanding.

What is universe?</h3>
The term "universe" (from the Latin "universus") refers to the entirety of space, time, and all of its objects, including galaxies, planets, stars, and other types of matter and energy. The prevailing cosmological explanation for the universe's formation is the Big Bang theory. This hypothesis states that the universe has been expanding ever since the Big Bang, which took place 13.7870.020 billion years ago. While it is uncertain how big the entire universe is in terms of space, it is possible to calculate the size of the observable universe, which has a current diameter of about 93 billion light-years.
Early cosmological conceptions of the cosmos were geocentric, with Earth as the centre, and were created by Greek and Indian philosophers.
