Revert back to my motivating question to start the second paragraph of
the introduction "Given these requirements, how do we X, Y, Z?"

This to me is much more engaging than the text that replaced it, and
motivating questions like this are not uncommon in JSS introductions.

The next sentence, "Most technical computing languages such as X, Y,
Z, and W" does not seem as correct as the simpler "Programming
languages X, Y, Z, and W" that I used previously.  X, Y, Z, and W do
not necessarily equate with "most technical computing languages", and
"technical computing languages" is more cumbersome than just saying
"programming languages".  What is technical computing compared to
non-technical computing, anyway?  Everything except VB macros?

We could change this to "programming langauges used for data analysis"
or similar if someone really doesn't like the simple straightforward
use of "programming languages" here.

Otherwise keep some of the grammar improvements made to these two
sentences.
