The Taklamakan lies in the Tarim Basin of Xinjiang in north-western China, in the heart of Central Asia. The Taklamakan is a cold, sandy desert ringed by high mountains: the Kunlun to the south, the Tian Shan to the north and the Pamirs to the west.

A simple periscope has two plane mirrors, and light reaches the eye only by bouncing off them. In a simple periscope, two plane mirrors are fixed parallel to each other at the two bends of a long tube, each tilted at 45° to its length.

A mixture of carbon monoxide and hydrogen is called synthesis gas, or syngas, because it is the starting material for making methanol and many other compounds.

This is sodium stearate, the sodium salt of a long-chain fatty acid, which makes it a soap and not a synthetic detergent.

This statement is false: water is a strongly polar molecule. In a water molecule the oxygen atom is much more electronegative than hydrogen, so it pulls the shared electrons towards itself and carries a partial negative charge, while the two hydrogens carry partial positive charges.

Argon has atomic number 18, and a neutral atom has as many electrons as protons, so it has 18 electrons.

X-rays have wavelengths of roughly 0.01 nm to 10 nm, so 1 nm sits right inside the X-ray band. The electromagnetic spectrum runs, from the shortest wavelength to the longest, as gamma rays, X-rays, ultraviolet, visible light, infrared, microwaves and radio waves.

Meiosis makes gametes that differ from one another, and fertilization joins a gamete from each of two parents, so every offspring gets a new mix of genes.

Work is W = F × d × cos θ, and when the angle θ between force and displacement is 90°, cos 90° = 0, so the work done is zero.

As an object comes in from far away towards C, its real, inverted image moves out from the focus towards C, and the two meet at C. For a concave mirror, an object at infinity forms its image at the focus F, and an object at the centre of curvature…

To just complete a vertical circle, a bob on a string needs a speed of at least √(5gL) at the lowest point, and √(5 × 10 × 0.5) = √25 = 5 m/s. A string can only pull, never push.

As Director of NIPER Raebareli she said the proposed Centre of Excellence would serve as a dedicated platform for structured training and certification in clinical research, and that bringing academic and industry expertise together would produce a model capable of being repeated in other regions and therapeutic areas.

It is described as the central government's flagship initiative for building a stronger biopharma ecosystem, and among its goals is the creation of a thousand clinical trial sites across the country; the partnership between NIPER Raebareli and AstraZeneca India directly serves that objective.

The partnership begins by adopting 25 clinical trial sites in emerging research geographies, assessing what each can do, and then giving the staff targeted training and mentoring while tightening documentation and the processes around ethics, safety and trial feasibility.

Promoting alternative development, including the growing of alternative crops in place of illicit ones, is a mandate the bureau carries under this policy, which is why the public dialogue at Malana village formed part of the operation rather than being an extra.

The Central Bureau of Narcotics is the country's apex drug law enforcement and regulatory agency and it sits under the Department of Revenue in the Ministry of Finance, a placement that surprises candidates and therefore makes a good question.

The Central Bureau of Narcotics carried out its destruction drive in Kullu district, clearing 5,165 acres, or 2,070 hectares, of illicit cannabis cultivation over one month.

The bonus was approved on the strength of the railways' performance in 2025-26, and the government cited a record freight loading of 1,670 million tonnes for that year together with a passenger count of nearly 7.41 billion.

That is the amount the Union Cabinet approved for paying a bonus of 78 days' wages to railway employees, and it is spread across 11,40,770 employees.

The Union Cabinet cleared a Productivity Linked Bonus equal to 78 days' wages for railway employees, and this is the figure every other number in the decision hangs on: the total sanctioned amount, the per-employee ceiling and the count of employees covered are all tied to the same 78 days.
