International Criminal Court
The ICC is an intergovernmental organization and international tribunal that sits in The Hague, Netherlands.
It is the first and only permanent international court with jurisdiction to prosecute individuals for the international crimes of genocide, crimes against humanity, war crimes, and the crime of aggression.
It is intended to complement existing national judicial systems and it may therefore exercise its jurisdiction only when national courts are unwilling or unable to prosecute criminals.
The ICC lacks universal territorial jurisdiction, and may only investigate and prosecute crimes committed within member states, crimes committed by nationals of member states, or crimes in situations referred to the Court by the UNSC.

About the Ranking

It is the annual ease of doing business index of states and UTs of India based on the completion percentage scores of action items points of annual Business Reforms Action Plan (BRAP) under the Make in India initiative.
This ranking is based on the implementation of the business reform action plan.
Some of the key focus areas are access to information and technology, the setting up of a single-window system, construction permit enablers and land administration, according to DPIIT.
It based on the progress of states in completing annual reform action plan covering 8 key areas.
The top ten states under the State Reform Action Plan 2019 are:

Andhra Pradesh
Uttar Pradesh
Telangana
Madhya Pradesh
Jharkhand
Chhattisgarh
Himachal Pradesh
Rajasthan
West Bengal
Gujarat

What exactly was detected?
It was a signal from a gravitational wave, a relatively new field of discovery.
Gravitational waves are invisible ripples that form when a star explodes in a supernova; when two big stars orbit each other; and when two black holes merge.
Travelling at the speed of light, gravitational waves squeeze and stretch anything in their path.
Detecting gravitational waves
Gravitational waves were proposed by Albert Einstein in his General Theory of Relativity over a century ago.
It was only in 2015, however, that the first gravitational wave was actually detected — by LIGO. Since then, there have been a number of subsequent detections of gravitational waves.
The signal detected at LIGO and Virgo, as described by the LIGO Collaboration, resembled “about four short wiggles” and lasted less than one-tenth of a second.
Where did it come from?
Subsequent analysis suggested that GW190521 had most likely been generated by a merger of two black holes. The signal likely represented the instance that the two merged.
It was calculated to have come from roughly 17 billion light-years away, and from a time when the universe was about half its age.

Explanation:

India is on the brink of an acute water crisis, which has, to an extent, fabricated a looming threat of trans-boundary water conflicts. The conflict on the Mandovi / Mahadayi River— flowing through Goa, Karnataka and Maharashtra— is one such example.

Kalasa-Banduri Project
The project undertaken by the Karnataka government proposes to divert Mandovi river water from Kalasa and Banduri canals into the Malaprabha river in the state.
The project received clearance from the Centre in 2002. It aims to construct a total of 11 dams on the river Mandovi.
The diversion of water from Kalasa and Banduri nullahs, however, has been the point of contention between Karnataka and Goa, with the latter claiming it would strip the state of its flora and fauna.

The conflict
The Mandovi originates from Karnataka’s Belgaum district.
The Mandovi river basin falls into the states of Goa, Karnataka and Maharashtra.
The river is 81 kilometres (km) in length; 35 km of which flows in Karnataka, 1 km in Maharashtra and 45 km in Goa.
The seeds of the conflict were sowed over 40 years ago: In 1985, Karnataka initially explored a 350 megawatt-hydro-electric project to divert 50 per cent of the Mandovi river water in Karnataka for irrigation.
The plan was also to allow a steady flow of water from the power project’s storage dam after using the water for irrigation purposes in Karnataka.
This would have served to drinking water and irrigation purposes in Goa as well.
