Astronomy is the study of space, including celestial bodies such as stars, planets, galaxies, and other objects that exist beyond Earth's atmosphere. It involves the observation and analysis of these objects to understand their composition, behavior, and interactions. Astronomers use various tools and techniques, such as telescopes and satellites, to gather data and make discoveries about the universe. By studying space, astronomers aim to unravel the mysteries of the cosmos and expand our knowledge of the vastness and complexity of the universe.

The Pacific Ocean is the largest ocean in the world. It covers a vast area, stretching from the western coast of the Americas to the eastern coast of Asia and Australia. It is also the deepest ocean, with the Mariana Trench, the deepest point on Earth, located in its waters. The Pacific Ocean is known for its diverse marine life and important role in regulating the Earth's climate.

Jupiter is the correct answer because it is the largest planet in our solar system. It has a diameter of about 143,000 kilometers, which is more than 11 times the diameter of Earth. Jupiter's massive size is due to its composition, primarily made up of hydrogen and helium gases. It also has a strong gravitational pull, with more than twice the mass of all the other planets combined. Jupiter's size and gravitational force make it a dominant force in our solar system.

The symbol K is used to represent the element potassium in the periodic table. Potassium is a chemical element that is essential for various biological processes in the human body.

A pentagon is a geometrical shape with 5 sides and 5 angles. This is because the prefix "penta-" means five, and a polygon with five sides is called a pentagon. Each side of a pentagon connects two vertices, and each vertex forms an angle with the two adjacent sides. Therefore, a pentagon has 5 sides and 5 angles.

Albert Einstein is the correct answer because he is the scientist who developed the theory of relativity. His theory revolutionized our understanding of space, time, and gravity, and it is one of the most important scientific theories in history. Einstein's theory of relativity has been confirmed by numerous experiments and observations, and it continues to be a cornerstone of modern physics.

The correct answer is "I have gone there." This is a present perfect continuous sentence because it uses the present perfect tense ("have gone") to indicate an action that started in the past and is still ongoing or has just been completed. The other options do not use the present perfect continuous tense.
