Solution

In sentence 2, the comparison is not made between two similar entities. The statement can be repaired in two ways

1. By removing not - "The hundreds of unsuccessful candidates would fault their own inadequacies in an open system, but end up nursing grievances against the system and the polity in a quota based system".

2. By keeping the comparison of their own faults in both the parts of the sentence - "The hundreds of unsuccessful candidates would not fault their own inadequacies in an open system, but end up accepting the same in a quota based system"

In sentence 5, current has been mis-spelled as currant which changes the meaning entirely and is contextually incorrect.
2 sentences have issues.
Hence, the correct answer is option 2.
