Determine the correctness or otherwise of the following Assertion [a] and the Reason [r]

Assertion: Ab initio gene finding algorithms that predict protein coding genes in eukaryotic genomes are not completely accurate.

Reason: Eukaryotic splice sites are difficult to predict.

  1. Both [a] and [r] are false
  2. [a] is true but [r] is false
  3. Both [a] and [r] are true and [r] is the correct reason for [a]

In a detailed study of annual crow births in India, it was found that there was relatively no growth during the period $2002$ to $2004$ and a sudden spike from $2004$ to $2005$. In another unrelated study, it was found that the revenue from cracker sales ... birth rate. If cracker sale declines, crow birth will decline. Increased birth rate of crows will cause an increase in the sale of crackers.
