Arrange the following words in a logical sequence. 1. Grass 2. Curd 3. Milk 4.…

Concept: In an 'arrange the words in a logical sequence' reasoning question, the words must be ordered by their real-world cause-and-effect / production chain — each item is the direct result of the one immediately before it, starting from the original source and ending at the final product.

Application:

1. Cow is the source — the starting point of this chain.

2. The cow consumes Grass.

3. After grazing, the cow yields Milk.

4. Milk is set and processed to make Curd.

5. Curd is churned to produce Butter.

So the production chain reads Cow, Grass, Milk, Curd, Butter — that is, 4, 1, 3, 2, 5.

Cross-check: tracing the chain backwards confirms the same order — Butter is churned from Curd, Curd is set from Milk, and Milk comes from the Cow after it grazes on Grass — so no step can be swapped without breaking the cause-and-effect link.
