When glass breaks, the cracks propagate at extremely high speeds due to the rapid release of stored elastic energy. Scientific studies have measured crack speeds in glass reaching approximately 3,000 mph (about 1,300 m/s), which is near the theoretical maximum speed for crack propagation in brittle materials. This phenomenon occurs because glass is an amorphous solid that fractures catastrophically when its elastic limit is exceeded.

The Wright Brothers' historic first airplane was tested at Kitty Hawk, North Carolina, which is why their aircraft became known as the 'Kitty Hawk.' The location was chosen for its windy conditions and soft sand dunes, which provided ideal conditions for flight testing and safer crash landings.

Orissa (now Odisha) has historically had one of the highest percentages of population living below the poverty line among Indian states. This is due to factors including lower industrial development, high tribal population in remote areas, and frequent natural disasters affecting coastal regions. While other states listed also have BPL populations, Orissa consistently ranked highest in BPL ratios during the period this question refers to.

ISO stands for International Organization for Standardization, which creates and publishes international standards for various industries and products. Option D is the closest correct answer, though it uses 'Organisation' instead of 'Organization' and places 'Standards' before the organization name. Options A, B, and C are incorrect - ISO has nothing to do with insurance or space, and is not an integrated security body.

Green Revolution in India centered on three key inputs: high-yielding seed varieties, chemical fertilizers, and expanded irrigation infrastructure. These three components worked together to dramatically increase agricultural productivity, particularly for wheat and rice. Option A correctly identifies all three pillars.
