Parasites need a host. If a host tries to get rid of the parasite or kill it, then the parasite either has to leave the body or die.

The correct answer is "increased activity of the right hippocampal formation".
Hippocampus is a brain area which is part of the limbic system and is located below the cerebral cortex. Humans have two hippocampi, one in each side of the brain. Hippocampus is responsible for the formation of long-term memories, by participating in the consolidation of short-term to long-term memory. It also plays a very important role in spatial memory and orientation.
The task that this experienced cab-driver is asked to perform is related to spatial navigation and orientation abilities. The right hippocampus has been shown to participate in the formation of memory for locations in specific environments, while the left hippocampus has been shown to be involved in autobiographical and episodic memory. As a result, the PET scan will show an increased activity of the right hippocampus.  
        
             
        
        
        
(Initial individuals + newborn individuals) - dead individuals = total individuals
Growth rate = (total individuals/initial individuals) * 100
Population growth rate = new percentage minus 100%
Calculations
(1000 + 500) - 200 = 1500 - 200 = 1300
Growth rate = (1300/ 1000) * 100 
 = 1.3 * 100
 = 130%
Population growth rate = 130% - 100%
 = 30% per year if it is uniform
