A. the length of day and year are similar to Earth

B. Mars has seasons like Earth

C. Mars tilts on an axis of rotation like Earth

D. all of the above

2. The mind is altered by each new event it encounters.

true

false

3. The neocortex overrides the primitive actions of the reptilian brain and limbic system, giving rise to rational thinking.

true

false

4. Warming Mars could be accomplished by

A. using PFCs

B. positioning mirrors to reflect sunlight onto the planet

C. transferring nitrogen from Venus or Titan

D. all of the above

Answer 1

1. A Martian day is just 40 minutes (approximately) longer compared to a day on Earth,
and a Martian year (687 days) is longer than a year on earth (365 days),
Since Mars is further from the Sun compared to the Earth. Mars’s axial tilt is 25 degrees,
just a fraction away from Earth’s 23.5 degrees. Mars has seasons because of this tilt, just like the Earth.

correct option is (D) all of the above

2. New information or new encounters can interfere with the old information and can alter the memory.

therefore, the given statement is TRUE

3. The rational decision would be impossible without neocortical (thinking/rational brain) override of primitive actions of the reptilian brain and limbic system (at the times of perceived threat, the brain overrides the rational brain)

Therefore, the given statement is TRUE

4. Warming Mars could be accomplished by

a. greenhouse gas like PFCs

b. placing Orbital Mirrors

correct option is (D) all of the above
