Maximising lamb survival in an outdoor lambing flock

In one year, a farmer runs 30 000 sheep on his property. In the next year, because of the drought, the farmer reduces his flock by 37%.The number of sheep he has after the fall in numbers is:

Cattle:herd :: Sheep: ?

Cattle : Herd :: Sheep : ?

When examining the health of a grazing sheep, the behaviour of the entire flock should first be assessed. Question 4Select one:TrueFalse

Imagine a situation where farmers can graze their cows on a shared grassy area for free. The only constraint is that, in order the grass to be in good conditions, no more than 100 cows should go. Given that the total number of farmers living close by is 100:The optimal choice for each farmer will be to bring just one cow to the grass.Every farmer will be selfish and bring more than one cow so the grass will be totally damaged.All farmers will cooperate and the grass will be perfectly preserved.There will be exactly one farmer bringing more than one cow so the grass will be only slightly damaged.
