The Inca Civilization used quipu - a system of knotted strings - for recording numbers and keeping records. This was their primary method of numerical record-keeping since they did not have a written language.

The ancient Egyptians created the first known written numerals on papyrus. They developed a hierarchical decimal numeral system that they used extensively in administration and record-keeping.

System On Chip (SoC) is the computer architecture where all components of a computer system are integrated onto a single chip. This is the awaited future architecture that represents the ultimate miniaturization of computing systems.

Vitamin A deficiency causes retardation of growth in children. Vitamin A is essential for normal growth and development, and its deficiency leads to stunted growth and other developmental issues.

Around 3000 BC, both Babylonians and Egyptians began using advanced mathematics including arithmetic, algebra and geometry for practical purposes like taxation, construction and astronomy. This marked a significant advancement beyond basic counting and measurement.

By 900 BC, Europe had accepted Arithmetic and Algebra from India and eastern countries. This mathematical knowledge transfer occurred through trade routes and cultural exchanges, significantly influencing European mathematical development.

Vitamin E deficiency causes loss of fertility in both males and females. Vitamin E is important for reproductive health, and its deficiency can lead to fertility problems and reproductive system disorders.

Vitamin B1 (Thiamine) deficiency causes Beriberi, a disease characterized by nerve and muscle damage, cardiovascular problems, and edema. Beriberi was common in populations whose diet consisted mainly of polished rice.

The Pythagorean philosophy was based on the belief that whole numbers were the cause of various qualities of man and matter. Pythagoreans believed that 'all is number' and that numerical relationships explained the universe.

Thales, Pythagoras, and Plato were Greek philosophers who studied in Egypt and incorporated Egyptian mathematical knowledge into their work. Thales is credited with introducing Egyptian geometry to Greece, Pythagoras spent time in Egypt learning from priests, and Plato also studied Egyptian traditions. Option D incorrectly lists "Pyhtagoras" (typo) and includes Euclid/Archimedes who came later.
