What is the primary goal of SETI?

  1. To confirm the existence of extraterrestrial life.

  2. To establish communication with alien civilizations.

  3. To study the origins and evolution of life in the universe.

  4. To search for habitable planets outside our solar system.

Show answer
Correct Option: D
Explanation:

SETI aims to detect signs of intelligent life beyond Earth, including the search for habitable planets and the analysis of radio signals from space.

Which method is commonly used in SETI to detect radio signals from extraterrestrial civilizations?

  1. Optical SETI

  2. Laser SETI

  3. Radio SETI

  4. Gravitational Wave SETI

Show answer
Correct Option: C
Explanation:

Radio SETI involves searching for narrowband radio signals that could be indicative of intelligent transmissions.

What is the Drake equation used for in SETI?

  1. To calculate the probability of finding intelligent life in the universe.

  2. To estimate the number of habitable planets in a galaxy.

  3. To determine the distance to the nearest star system.

  4. To predict the age of the universe.

Show answer
Correct Option: A
Explanation:

The Drake equation is a probabilistic argument used to estimate the number of advanced civilizations in the Milky Way galaxy.
