Given below are the list of some of the most rare species on our planet (Column X) and the regions of the world where they occur (Column Y). Column X Name of the organism Column Y Region of occurrence A. Saola i. Tianshan mountains B. Ili Pika ii. Vietnam C. Greater Bamboo Lemur iii. Sahara Desert D. Addax iv. Madagascar Which one of the following options represents all correct matches between Column X and Column Y?
A - ii; B - i; C - iv; D - iii
This question asks us to correctly match a list of rare species with the regions of the world where they are found. We are given two columns, Column X with the names of organisms and Column Y with the regions of occurrence.
| Column X: Name of the organism | Column Y: Region of occurrence |
|---|---|
| A. Saola | i. Tianshan mountains |
| B. Ili Pika | ii. Vietnam |
| C. Greater Bamboo Lemur | iii. Sahara Desert |
| D. Addax | iv. Madagascar |
Species Regions Explained
Let's analyze the correct matches for each rare species based on their known habitats:
- Saola (A): The Saola is a critically endangered mammal native to the Annamite Mountains of Vietnam and Laos. Therefore, it matches with Vietnam (ii).
- Ili Pika (B): The Ili Pika is a small mammal found in the Tianshan Mountains region of China. Therefore, it matches with Tianshan mountains (i).
- Greater Bamboo Lemur (C): Lemurs are primates endemic to the island of Madagascar. The Greater Bamboo Lemur is found in Madagascar. Therefore, it matches with Madagascar (iv).
- Addax (D): The Addax, also known as the white antelope, is a desert antelope found in the Sahara Desert region of Africa. Therefore, it matches with the Sahara Desert (iii).
Correct Matches Summary
Based on the analysis, the correct pairings are:
- A - ii (Saola - Vietnam)
- B - i (Ili Pika - Tianshan mountains)
- C - iv (Greater Bamboo Lemur - Madagascar)
- D - iii (Addax - Sahara Desert)
This set of matches corresponds to the correct option.
