How many Bio-diversity Hot-spots are found on the world map?

Question

Accepted Answer

The correct answer is Option 2: 18.

Explanation:

While the number of recognized biodiversity hotspots has increased over time, the question implies a specific historical context or a particular definition being used. The number 18 is associated with the initial identification of biodiversity hotspots by Norman Myers in 1988. He identified 10 tropical forest "hotspots" and later added 8 more, bringing the total to 18. Therefore, within the context of the early identification and conceptualization of biodiversity hotspots, 18 is a valid and historically significant number.

Why the other options are incorrect:

*   **Option 1: 14:** There is no widely recognized or historically significant classification of biodiversity hotspots that totals 14.

*   **Option 3: 20:** While the number of hotspots has grown over time, 20 is not a number that is associated with the initial identification of biodiversity hotspots.

*   **Option 4: 24:** There is no widely recognized or historically significant classification of biodiversity hotspots that totals 24.
