Science & Technology MCQs

A qubit (quantum bit) is the basic unit of quantum information, analogous to a bit in classical computing, but capable of existing in multiple states simultaneously due to superposition.

AI tools are highly effective in analyzing medical images and tissue samples, making them invaluable assistants for radiologists (interpreting scans) and pathologists (analyzing biopsies).

Deep Learning, particularly convolutional neural networks (CNNs), excels at pattern recognition in complex data like medical images (X-rays, MRIs, CT scans) for identifying anomalies indicative of cancer.

AI tools can analyze vast amounts of medical data, such as images and patient records, much faster and often with higher accuracy than humans, leading to earlier and more precise diagnoses.

Lunar sample return missions typically aim to collect regolith (lunar soil) and rock fragments to study the Moon's geological history and composition.

Chandrayaan-3 successfully achieved a soft landing on the lunar south pole region in August 2023, deploying the Pragyan rover.

The primary objective of Chandrayaan-4 is a lunar sample return mission, aiming to bring back lunar soil and rock samples to Earth for scientific analysis.

Quantum sensors rely on quantum states, such as superposition and entanglement, to detect minute changes in physical quantities.

Quantum sensors are highly effective in navigation (GPS-free) and geophysics (detecting underground structures) due to their extreme sensitivity.

Quantum sensors utilize quantum mechanical phenomena to achieve measurement precision far beyond the limits of classical sensors.
