So you don't actually want to address a legitimate question.
No, I don't want to address a question posed in bad faith.
Let's start by modestly noting that I routinely got the top score on Latin tests in high school (this was worth a small box of chocolates!). Someone applying the concept of "intelligence" might predict that I would also do well in math class. The traditional explanation for this given by Latin teachers is that learning Latin trains the mind to think logically, and getting high scores on Latin tests means that the training has taken. The intelligence-based explanation is that Latin and math are two of many tasks subject to the influence of g, the "general factor".
Moving to a more general level, the observation is that for many, many tests that appear to involve "mental abilities" to a greater or lesser degree, a person's score on any one of them is predictive of the same person's score on all the others. It's rare to find someone who is good at one and bad at another; instead, people tend to be uniformly good or uniformly bad (known in the literature as the phenomenon of the "positive manifold"). This suggests that there's one quality driving all the results, which we can call "intelligence", since that's the label commonly applied to people who tend to do well on those types of tests.
Corrections are of course welcome.
