a) to find alternative explanations for the process of evolution, Jean-Baptiste Lamarck repeated his initial experiment on mollusks once in every 4 weeks but received exactly the same results 3 times in a row.

b) alternative explanations for the process of evolution, Jean-Baptiste Lamarck repeated his initial experiment on mollusks once in every 4 weeks but received exactly the same results in a row 3 times.

c) alternative explanations for the process of evolution, Jean-Baptiste Lamarck repeated his initial experiment on mollusks every 4 weeks but received the same results 3 times in a row.
d) alternative explanations for the process of evolution, Jean-Baptiste Lamarck repeated his initial experiment on mollusks every 4 weeks but received exactly the same results 3 times in a row.
e) alternative explanations for the process of evolution, Jean-Baptiste Lamarck repeated his initial experiment on mollusks every 4 weeks but he received the same identical results 3 times in a row.

my doubt is which is better every 4 weeks or once in every 4 weeks

'every 4 weeks' is same as 'once in every 4 weeks' in terms of meaning

the former is preferred in gmat because it is less wordy compared to the later!

hope it helps

the best way to get to the answer over here is removing the redundant part .
Exactly
.here v are already have same so no need of exactly ..that leaves C and E ..E again has same and identical.so wrong
