Jim made this incorrect diagram to represent the order in which four events took place on earth.. 1 primitive fish.. 2 primitve reptile. 3 giant insect. 4 primitive horse. the flaw in jim's diagram can be corrected by interchanging the positions of . a] giant insect and primitive horse. b] primitive reptiles and giant insect. c] primitive fish and primitive reptile. d] primitive horse and giant insect. .

The actual answer (sorry for the late reply, but this is for the rest of the people coming afterwards) would actually be B) Switch primitive reptile with primitive insect. Insects came before any reptiles.

Option (B)

Explanation:

The above given question is based on the geological time scale, which represents the sequential arrangement of major and minor events that has taken place on earth right from the formation of the earth.

From the given options, primitive fishes first appeared on earth about 530 million years back, during the time of Cambrian. Next to this, the giant insects appeared some 410 million years back during the early Devonian period. After this, the reptiles appeared about 310 million years back during the late Carbonaceous period. And lastly, the horses appeared about 55 million years back during the time of Eocene period.

Thus, the position of primitive reptiles and giant insects must be interchanged.

Hence, the correct answer is option (B).

the answer is:
