Problem: Please answer a question about the following article about Macintosh:
Two days after "1984" aired, the Macintosh went on sale, and came bundled with two applications designed to show off its interface: MacWrite and MacPaint. It was first demonstrated by Steve Jobs in the first of his famous Mac keynote speeches, and though the Mac garnered an immediate, enthusiastic following, some labeled it a mere "toy." Because the operating system was designed largely around the GUI, existing text-mode and command-driven applications had to be redesigned and the programming code rewritten. This was a time-consuming task that many software developers chose not to undertake, and could be regarded as a reason for an initial lack of software for the new system. In April 1984, Microsoft's MultiPlan migrated over from MS-DOS, with Microsoft Word following in January 1985. In 1985, Lotus Software introduced Lotus Jazz for the Macintosh platform after the success of Lotus 1-2-3 for the IBM PC, although it was largely a flop. Apple introduced the Macintosh Office suite the same year with the "Lemmings" ad. Infamous for insulting its own potential customers, the ad was not successful.
Why did many software developers choose not to redesign the Mac operating system and rewrite the programming code?
A: This was a time-consuming task

There are several major exceptions on tuition fees. In many European countries, it is possible to study without tuition fees. Public universities in Nordic countries were entirely without tuition fees until around 2005. Denmark, Sweden and Finland then moved to put in place tuition fees for foreign students. Citizens of EU and EEA member states and citizens from Switzerland remain exempted from tuition fees, and the amounts of public grants granted to promising foreign students were increased to offset some of the impact.

Until what year were public universities in nordic nation free of tuition?
Answer: around 2005

Problem: Track lighting, invented by Lightolier, was popular at one period of time because it was much easier to install than recessed lighting, and individual fixtures are decorative and can be easily aimed at a wall. It has regained some popularity recently in low-voltage tracks, which often look nothing like their predecessors because they do not have the safety issues that line-voltage systems have, and are therefore less bulky and more ornamental in themselves. A master transformer feeds all of the fixtures on the track or rod with 12 or 24 volts, instead of each light fixture having its own line-to-low voltage transformer. There are traditional spots and floods, as well as other small hanging fixtures. A modified version of this is cable lighting, where lights are hung from or clipped to bare metal cables under tension.
Who invented track lighting?
The answer is the following: Lightolier
