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.

Jobs was diagnosed with a pancreatic neuroendocrine tumor in 2003. The other options (brain, blood, heart) are factually incorrect. This cancer eventually led to his death in 2011.

Michael Dell famously suggested in 1997 that Apple should be shut down; Jobs led Apple's remarkable turnaround, eventually surpassing Dell in market cap. 'Won' refers to this vindication. However, 'face off where he WON' is ambiguous phrasing.

Jobs co-founded Apple in 1976 and returned as CEO in 1997. The question asks when his 'service as CEO begin and happen'; both dates are correct phases. The '1996' option likely refers to Apple's 1996 acquisition of NeXT that brought Jobs back.

Steve Jobs was named Financial Times Person of the Year in 2010 for 'remaking three industries' with iPod, iPhone, and iPad. 2010 marked the peak of his post-return influence before his death in 2011.

Jobs was known as an aggressive salesman and marketer with his 'reality distortion field', legendary persuasive ability. 'Geek' and 'nerd' understates his business acumen; 'ICON' is too vague for top circles.

The Big Bang theory explains that the Universe began in a hot, dense state and has been expanding ever since. It's supported by evidence like cosmic microwave background radiation, redshift of galaxies, and the abundance of light elements. Steady State theory (option B) proposed that the Universe has always existed and looks the same at all times, but this was disproven.

The Hubble Space Telescope was launched in 1990 through a collaboration between NASA (United States) and ESA (European Space Agency). NASA provided the spacecraft and its launch, while ESA contributed key instruments and scientific support.

The James Webb Space Telescope (JWST), launched in December 2021, is designed to succeed Hubble. It observes primarily in infrared wavelengths, allowing it to see through dust clouds and observe the earliest galaxies in the universe.

The Hubble Constant (H₀) measures the rate of expansion of the universe. By knowing the expansion rate, scientists can estimate the age of the universe by running the expansion backwards in time. A higher H₀ implies a younger universe.

The Oscillating (or Pulsating) Universe theory proposes that the universe undergoes endless cycles of expansion (Big Bang) and contraction (Big Crunch). This differs from the standard Big Bang theory (single expansion) or Steady State theory (continuous creation).

Isotones are atoms of different elements that have the same number of neutrons in their nuclei. This differs from isotopes (same protons, different neutrons) and isobars (same mass number but different proton/neutron counts).

Under uniform gravitational acceleration (neglecting air resistance), a projectile follows a parabolic path. The horizontal velocity remains constant while vertical velocity changes linearly due to gravity, creating a parabolic trajectory.

A vernier caliper is specifically designed to measure the distance between two opposing sides of an object (external dimensions) with high precision, typically to 0.02mm or better. It has two sets of jaws - one for external measurements and one for internal measurements. A dial indicator measures small distances or deviations, while a profile gauge replicates contours rather than measuring dimensions.
