Additional Information 

The correct answer is Mirage.

• To a distant observer, the light appears to be coming from somewhere below the ground.
• The observer naturally assumes that light is being reflected from the ground, say, by a pool of water near the tall object.
• Such inverted images of distant tall objects cause an optical illusion to the observer.
• This phenomenon is called a mirage.
•  The optical illusion which occurs mainly in the desert during hot summer is based on the principle of TIR i.e total internal reflection.
• This type of mirage is especially common in hot deserts.

Additional Information

• Total Internal Reflection (TIR): When a ray of light goes from denser to the rarer medium it bends away from the normal and as the angle of incidence in denser medium increases, the angle of refraction in the rarer medium also increases and at a certain angle, angle of refraction becomes 90°, this angle of incidence is called critical angle (C).
• When the Angle of incidence exceeds the critical angle then the light ray comes back into the same medium after reflection from the interface. This phenomenon is called Total internal reflection (TIR).
• Conditions for TIR: 
  1. The ray must travel from denser medium to rarer medium.
  2. The angle of incidence 'i' must be greater than the critical angle C.

The correct answer is Governor.

Key Points

• The Lokayukta presents the annual report in Rajasthan to Governor.
  • The Lokayukta and the Up-Lokayukta shall present annually a consolidated report on the performance of their functions under this Act to the Governor.

  • The Lokpal Act was passed by the Parliament of India in December 2013.
  • It provides for the appointment of a Lokayukta “to investigate and report on allegations or grievances relating to the conduct of public servants.”
  • The Chief Minister selects a person as the Lokayukta after consultation with the High Court Chief Justice, the Speaker of the Legislative Assembly, the Chairman of the Legislative Council, Leader of Opposition in the Legislative Assembly, and the Leader of Opposition in the Legislative Council.
  • The appointment is then made by the Governor.
  • Once appointed, Lokayukta cannot be dismissed nor transferred by the government, and can only be removed by passing an impeachment motion by the state assembly.

The correct answer is Primary key.

Key Points

• The foreign key is not necessarily the primary key in its current table.
  • It only has to contain the same information that is held in another table’s primary key.
  • Foreign keys are the columns of a table that points to the primary key of another table. They act as a cross-reference between tables.

Additional Information​ 

• A report generator is a computer program whose purpose is to take data from a source such as a database, XML stream or a spreadsheet, and use it to produce a document in a format which satisfies a particular human readership.
• The data dictionary is a set of information describing the contents, format, and structure of a database and the relationship between its elements, used to control access to and manipulation of the database.
• Schema objects are logical structures created by users. Objects such as tables or indexes hold data or can consist of a definition only, such as a view or synonym.
