Question Discussion & Solution

Concept:

The Android operating system was developed by Google for use in all of its touchscreen devices, tablets, and cell phones. This operating system was first developed by Android, Inc., a software company located in Silicon Valley before it was acquired by Google in 2005

The first public release of Android 1.0 occurred with the release of the T-Mobile G1 (aka HTC Dream) in October 2008. Android 1.0 and 1.1 were not released under specific code names.

Android name with their respective versions

The correct answer is 68 Assembly Constituencies.

• As of June 2020, the state of Himachal Pradesh has been divided into 68 Assembly Constituencies.

Key Points

• Himachal Pradesh:
  • In 1970, the Union Territory of Himachal Pradesh was elevated to the status of the state.
  • Its summer capital is Shimla.
  • Its winter capital is Dharamshala.
  • It has a total of 4 Lok Sabha seats and 3 Rajya Sabha seats.
  • Current Governor: Bandaru Dattatreya
  • Current Chief Minister: Jai Ram Thakur

Flood is overflow of water. In the same way, drought is a continuous dry period of weather.

The correct answer is Al2O3.

Key Points

•  Al2O3  reacts with acids and bases.
  • Aluminum oxide (Al2O3) is an amphoteric substance.
  • The amphoteric substance is a substance that can react with both acids and bases usually to produce salt and water.
  • Aluminium oxide therefore can react with both acids as well as bases. We will take the example of its reaction with hydrochloric acid (strong acid) and sodium hydroxide (strong base).
  • When mixed with these two compounds aluminium oxide either acts like  acid with a base and a base with an acid.

Additional Information

• Al₂O₃ + 6 HCl → 2 AlCl₃ + 3 H₂O (acts like a base)
• Al2O3 + 2 NaOH + 3 H₂O → 2 NaAl(OH)₄ (sodium aluminate) (acts like an acid)
• On reacting Al2O3 with HCl, we get Aluminium Chloride as the salt and water as a by-product.
  • Likewise, the reaction between NaOH ( Strong Base) and Al₂O₃ results in the formation of Sodium Aluminate as salt and water.

The pattern followed is/:

For this question, the logic for "SURVIVE is VXUYLYH" is given below-

Similarly,

We will apply the same logic on MONSOON as-

Hence, Option (1) is correct.
