Answer:  Option A - An endangered species native to the North Africa and Europe

Explanation:

• The Northern bald ibis, once nearly extinct, has been successfully revived through conservation efforts including breeding and rewilding.
• This bird is native to North Africa and Europe, and scientists are using microlight aircraft to train them for migration.
• The species is not found in North America or the Himalayan region, and it is not known for bright red plumage or a coastal habitat.

Answer:  Option C - Himachal Pradesh

Explanation:

• Himachal Pradesh is the first state in India to raise the minimum marriage age for women from 18 to 21 years through the Prohibition of Child Marriage (Amendment) Bill, 2024.
• This move aims to enhance gender equality and improve opportunities for education and personal development.

Answer:  Option B - Dopamine

Explanation:

• Parkinson's disease is primarily associated with a deficiency in dopamine, a neurotransmitter crucial for coordinating smooth and controlled muscle movements.
• The disease affects the substantia nigra, a brain region responsible for dopamine production.
• As dopamine levels decrease, patients experience motor symptoms such as tremors, stiffness and slow movement.
• While other neurotransmitters like serotonin and acetylcholine are involved in various neurological functions, dopamine deficiency is central to Parkinson's disease.

Answer:  Option D - Gradient descent optimisation

Explanation:

• Gradient descent optimisation is the primary mechanism through which machine learning models improve performance.
• It iteratively adjusts model parameters to minimise the loss function, guiding the model towards better predictions.
• By reducing the error between predicted and actual values, gradient descent helps in refining the model's accuracy and efficiency, crucial for effective machine learning applications.

Answer:  Option C - Collision of the Indian Plate with the Eurasian Plate

Explanation:

• The Tibetan Plateau's formation is primarily due to the collision between the Indian Plate and the Eurasian Plate.
• This tectonic activity, which began around 50 million years ago, has resulted in the uplift of the plateau, creating the world's highest and largest plateau.
• The ongoing collision continues to influence seismic activity and topographical changes in the region, contributing significantly to its geological features.
