2a. Radford and his team got the idea to paint markings on cows because they noticed that spotted cows were attacked less frequently than plain cows. True or false

False.

Explanation:

Radford and his team performed an experiment on cows in Botswana. Botswana is a country in Southern Africa, where cows left to roam freely are hunted by predators such as lions, tigers, etc. And, in return, the villagers would kill the predator who killed their cow.

To break this cycle, and save predators from getting extinct, Radford and his team decided to paint big eyes on the backside of cows. So, when predators saw these large eyes, they didn't kill those cows instead they predated the cows with no paintings.

Therefore, the given statement is false.
