Which one of the following factors is responsible for the spread of myxomatosis—a severe viral disease among rabbits?
Options:
Accepted Answer: (C) High population density of rabbits
Topic Covered: Biology and Environmental Science
Key Concept: Ecology, genetics, biotechnology and life processes
The correct choice follows from the standard scientific definition or process involved. “High population density of rabbits” matches the relevant biological, ecological, chemical or energy concept, while the alternatives conflict with the core principle.
The key is to apply the central fact, formula, definition or relationship tested in the question and then eliminate alternatives that do not satisfy it.
