Emperor Ashoka of the Mauryan dynasty conquered Kalinga (modern-day Odisha) in the Kalinga War (around 261 BCE). This conquest was significant because Kalinga had remained independent and had not been captured by any previous ruler in the Mauryan dynasty, including Chandragupta Maurya or Bindusara. The brutal war and its aftermath deeply affected Ashoka, leading to his conversion to Buddhism and adoption of pacifist policies.

Fish breathe through gills, which are specialized respiratory organs that extract oxygen dissolved in water. Gills are rich in blood vessels and have large surface areas for efficient gas exchange. As water flows over the gills, oxygen is absorbed into the bloodstream and carbon dioxide is released. Fins are for movement, lungs are for air-breathing vertebrates, and skin breathing is minimal in most fish species.

Charles Darwin wrote 'On the Origin of Species' (full title: 'On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life') published in 1859. This revolutionary book presented Darwin's scientific theory that populations evolve over generations through natural selection. It forms the foundation of evolutionary biology. Stephen Hawking is a physicist, Alexander Fleming discovered penicillin, and Louis Pasteur contributed to germ theory and vaccination.

Korea is known as the 'Land of Morning Calm' (Korean: Joseon, meaning 'morning fresh/calm'). This poetic nickname dates back to the Joseon Dynasty (1392-1910) and reflects the peaceful scenery of Korean mornings, particularly with mountain mists and sunrise over the landscape. The phrase was popularized by Western travelers and missionaries in the late 19th century. Japan is the 'Land of the Rising Sun', while Malaysia and Thailand have different epithets.

The term 'Adivasi' (meaning 'original inhabitants' in Sanskrit) was first used systematically by Thakkar Bappa (Amritlal Vithaldas Thakkar), a prominent social reformer and advocate for tribal rights in the early 20th century. He worked extensively for the welfare of tribal communities and popularized the term to refer to India's indigenous tribal populations. While Gandhi, Phule, and Ambedkar all worked for marginalized communities, Thakkar Bappa is specifically credited with the systematic use of 'Adivasi' for tribal peoples.

The Medulla Oblongata is a vital part of the human brain, specifically located in the brainstem. It controls critical autonomic functions including breathing, heart rate, and blood pressure. The medulla oblongata connects the brain to the spinal cord and regulates essential life-sustaining processes. It is definitely not part of the heart, liver, or lungs - though it controls functions related to these organs through neural connections.

A newly born infant has approximately 300 bones, which is significantly more than the 206 bones in an adult human skeleton. This difference occurs because many bones in infants are made of cartilage and haven't fused together yet. For example, the skull consists of several separate plates that eventually fuse, the spine has more vertebrae that merge, and the sacrum and coccyx are initially separate bones. The fusion process continues through childhood and adolescence, resulting in fewer but larger bones in adulthood.

Christopher Latham Sholes, along with partners Samuel Soule and Carlos Glidden, invented the first practical typewriter in 1867. Sholes' design, known as the Sholes and Glidden typewriter, was commercially produced by Remington and Company. The QWERTY keyboard layout, still used today, was also developed by Sholes to prevent jamming of commonly used letter combinations. Shockley worked on transistors, Pascal invented the mechanical calculator, and Waterman is associated with fountain pens.

Oncology is the branch of medicine that specializes in the study, diagnosis, treatment, and prevention of cancer. The term comes from the Greek word 'onkos' meaning bulk or mass, referring to tumors. Oncologists are medical doctors who treat cancer through various methods including chemotherapy, radiation therapy, immunotherapy, and surgery. Ornithology studies birds, mammalogy studies mammals, and pedology studies soil - making 'Cancer' the correct answer among the given options.
