  2. Bronze

  3. Iron

  4. Cotton
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The earliest human artifacts are stone tools dating back 2.5-3 million years to the Paleolithic era. This predates metal working (Bronze Age ~3300 BCE, Iron Age ~1200 BCE) and systematic use of plant fibers, making rock/stone the first material used by humans.

Multiple choice technology packaged enterprise solutions

IBR used for which of the following material Type?

  1. Finished Goods

  2. Raw Material

  3. Semi finished Material

  4. Packaging Material
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

IBR (Intercompany Billing Rate) is applied to Finished Goods when transferring products between related company entities. Raw materials, semi-finished materials, and packaging materials typically use other valuation methods like standard cost or moving average, as they are internal or intermediate goods rather than final products sold between companies.

Multiple choice technology

What was the active medium used in the first working laser ever constructed?

  1. A diamond block

  2. Helium-neon gas

  3. A ruby rod

  4. Carbon dioxide gas
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The first working laser, built by Theodore Maiman in 1960, used a synthetic ruby crystal as the lasing medium. The ruby rod was pumped by a flash lamp to produce the laser beam. Helium-neon and carbon dioxide lasers came later, and while diamond can lase, it wasn't used in the first laser.

Multiple choice

Which of the following substances is most elastic?

  1. Rubber

  2. Sponge

  3. Steel

  4. Glass

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Steel is the most elastic because it returns to its original shape after deformation (high elastic modulus). Rubber seems stretchy but shows plastic deformation, sponge has low recovery, and glass is brittle (not elastic).

Multiple choice

Dwelling houses were made up of _________.

  1. burnt bricks of low quality

  2. clay and iron

  3. burnt bricks of high quality

  4. clay and bronze

  5. bricks and iron
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Dwelling houses were made up of burnt bricks of high quality.

Multiple choice

Which of the following materials traps the heat during the greenhouse effect?

  1. plastic

  2. paper

  3. wood

  4. glass

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Glass is the material used in physical greenhouse structures to trap heat. It allows visible light to enter but blocks infrared radiation from escaping, similar to how greenhouse gases work in the atmosphere. This is why the atmospheric effect is called the 'greenhouse effect' - it's named after the glass structure used in gardening.
