The five traditional human senses are sight (vision), taste (gustation), hearing (audition), smell (olfaction), and touch (tactile). Crying is an emotional response and physical secretion, not a sensory modality.

Children have 20 primary teeth that erupt during early childhood and begin falling out around age 6-7, replaced by permanent teeth. The other options are incorrect: 30 is close to adult tooth count, while 18 and 10 are too few.

The human body is approximately 60-70% water by weight, with 70% being the commonly cited average for adults. Water is essential for cellular functions, temperature regulation, and biochemical processes. 95% is more characteristic of jellyfish, while 50% and 30% are too low for humans.

The average human heart beats approximately 100,000 times per day, based on a normal resting heart rate of 60-100 beats per minute. 1,000,000 is too high, 50,000 is too low, and 5,000 is far below actual physiological rates.

An otologist is a medical specialist who treats conditions of the ear, including hearing and balance disorders. A dermatologist treats skin conditions, a pediatrician treats children, and an ophthalmologist treats eye conditions. The prefix "oto-" refers to the ear.

98.6°F (37°C) is the widely accepted normal human body temperature, established by Carl Wunderlich in the 19th century. While recent studies suggest it may be slightly lower, 98.6°F remains the standard medical reference. 99°F and 100.1°F indicate fever, while 97.5°F is below normal.

Steve Jobs co-founded Apple (1976), Pixar (acquired 1986), and NeXT (1985). Atari was founded by Nolan Bushnell in 1972; Jobs worked there briefly before founding Apple but was not a co-founder.

Jobs faced genuine criticism for Apple's environmental record (later improved) and minimal public philanthropy compared to peers like Bill Gates. His signature turtleneck and jeans were iconic, not criticized, and aggressive salesmanship isn't a standard critique.

Jobs practiced Zen Buddhism after a 1974 trip to India, influenced by his guru Kobun Chino Otogawa. His spiritual beliefs shaped Apple's design philosophy emphasizing simplicity, intuition, and minimalism.

Jobs became Disney's largest individual shareholder (7%) after the 2006 Pixar acquisition. At Apple, he held significant shares as co-founder and CEO, though 'majority' is technically misleading for both companies.
