Authoritarian regimes, in strength ( 1), are static regimes where ( 2) a supreme leader assumes (3) know-it-all power and essence ( 4).

In the question below four words are given in bold. These four words are may not be in their correct position. The sentence is then followed by options with the correct combination of words that should replace each other in order to make the sentence grammatically and contextually correct. Find the correct combination of the words that replace each other.

To find the correct combination of words that need to be swapped to make the sentence grammatically and contextually correct, let us analyze the given sentence:
"Authoritarian regimes, in strength (1), are static regimes where (2) a supreme leader assumes (3) know-it-all power and essence (4)."

Let us examine the positions of the bold words:
1. strength (1)
2. know-it-all (3)
3. essence (4)

Let us evaluate swapping 1 and 4:
If we replace "strength" (1) with "essence" (4) and vice versa, the sentence becomes:
"Authoritarian regimes, in essence (1), are static regimes where (2) a supreme leader assumes (3) know-it-all power and strength (4)."

Let us check the contextual and grammatical correctness of this modified sentence:
- "Authoritarian regimes, in essence..." is a standard, grammatically correct, and highly appropriate contextual phrase meaning "by their very nature" or "basically".
- "...assumes know-it-all power and strength" is contextually fitting as it describes a leader assuming absolute power and capability/force (strength).
Therefore, swapping 1 and 4 makes the sentence grammatically and contextually correct.

Thus, the correct option is 1 -4 only.
