Which one of the following is not correctly matched ?

Question

Accepted Answer

Option 4 is the one that is not correctly matched because Probabilism is most closely associated with the work of *Carl Sauer*, not La Blache. While La Blache is a key figure in the development of possibilism (a related concept), probabilism, as a distinct approach, is more directly linked to Sauer's cultural ecology.

Here's why the other options *are* correctly matched:

*   **Option 1: Human Ecology - Barrows:** Harlan H. Barrows is indeed considered a key figure in the development of human ecology as a subfield of geography. He emphasized the relationship between humans and their environment.

*   **Option 2: Geographical Pivot of History - Mackinder:** Halford Mackinder is famous for his "Geographical Pivot of History" theory, often referred to as the Heartland Theory.

*   **Option 3: Stop and Go Determinism - G. Taylor:** Griffith Taylor is known for his concept of "Stop and Go Determinism" (also sometimes called Neo-Determinism), which suggests that the environment sets limits, but humans can adapt and modify their environment within those limits.
