a) Mars b) Moon c) Europa d) Titan

a) SpaceX, under the leadership of Elon Musk, has plans to send a crewed mission to Mars, aligning with its long-term goal of establishing a human settlement on the planet.

6. What is the primary function of CRISPR-Cas9 technology in genetics?

a) Gene sequencing b) DNA replication c) Gene editing d) Protein synthesis

c) CRISPR-Cas9 is a revolutionary gene-editing technology that allows for precise, directed changes to genomic DNA. It has been widely used for research purposes and holds potential for treating genetic disorders.

7. Which type of electromagnetic radiation has the shortest wavelength?

a) Infrared b) Ultraviolet c) Gamma rays d) X-rays

c) Gamma rays have the shortest wavelengths in the electromagnetic spectrum, which gives them the highest energy. They are used in medical treatments and emitted in nuclear reactions.

8. Quantum entanglement is a phenomenon where particles remain interconnected, allowing instant communication regardless of distance. This is often referred to as:

a) Quantum tunneling b) Quantum superposition c) Quantum coherence d) Quantum non-locality

d) Quantum non-locality refers to the phenomenon of quantum entanglement, where particles remain connected, and the state of one particle instantly influences the state of another, no matter the distance between them.

9. What is the main advantage of 5G technology over 4G?

a) Greater energy efficiency b) Increased data transfer speeds and lower latency c) Wider coverage area d) Reduced interference from other signals

b)5G technology offers significantly higher data transfer speeds and lower latency compared to 4G, enabling faster downloads, more reliable connections, and support for a larger number of devices.

10. In computer science, what does 'AI bias' refer to?

a) The tendency of algorithms to favor certain outcomes based on incorrect assumptions b) The ability of AI to learn and improve from experience c) The process of training AI models using biased data d) The tendency of AI to avoid making decisions

a) AI bias occurs when an AI model produces results that are systematically prejudiced due to erroneous assumptions in the machine learning process, often caused by biased data, leading to unfair outcomes.
