Problem: Macintosh:

Notwithstanding these technical and commercial successes on the Macintosh platform, their systems remained fairly expensive, making them less competitive in light of the falling costs of components that made IBM PC compatibles cheaper and accelerated their adoption. In 1989, Jean-Louis Gassée had steadfastly refused to lower the profit margins on Mac computers, then there was a component shortage that rocked the exponentially-expanding PC industry that year, forcing Apple USA head Allan Loren to cut prices which dropped Apple's margins. Microsoft Windows 3.0 was released in May 1990, the first iteration of Windows which had a feature set and performance comparable to the significantly costlier Macintosh. Furthermore, Apple had created too many similar models that confused potential buyers; at one point the product lineup was subdivided into Classic, LC, II, Quadra, Performa, and Centris models, with essentially the same computer being sold under a number of different names.

When was Microsoft Windows 2.0 released?  May 1990

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In his book The Crucifixion of Jesus, physician and forensic pathologist Frederick Zugibe studied the likely circumstances of the death of Jesus in great detail. Zugibe carried out a number of experiments over several years to test his theories while he was a medical examiner. These studies included experiments in which volunteers with specific weights were hanging at specific angles and the amount of pull on each hand was measured, in cases where the feet were also secured or not. In these cases the amount of pull and the corresponding pain was found to be significant.
Who wrote The Crucifixion of Jesus?
A: Frederick Zugibe


Context and question: The reasons for the strong Swedish dominance are as explained by Richard Sparks manifold; suffice to say here that there is a long-standing tradition, an unsusually large proportion of the populations (5% is often cited) regularly sing in choirs, the Swedish choral director Eric Ericson had an enormous impact on a cappella choral development not only in Sweden but around the world, and finally there are a large number of very popular primary and secondary schools (music schools) with high admission standards based on auditions that combine a rigid academic regimen with high level choral singing on every school day, a system that started with Adolf Fredrik's Music School in Stockholm in 1939 but has spread over the country.
What does Eric Erickson explain about Swedish dominance in choirs?
Answer: unanswerable

In 1211, the Jewish community in the country was strengthened by the arrival of a group headed by over 300 rabbis from France and England, among them Rabbi Samson ben Abraham of Sens. Nachmanides, the 13th-century Spanish rabbi and recognised leader of Jewry greatly praised the land of Israel and viewed its settlement as a positive commandment incumbent on all Jews. He wrote "If the gentiles wish to make peace, we shall make peace and leave them on clear terms; but as for the land, we shall not leave it in their hands, nor in the hands of any nation, not in any generation."
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was the 13th-century Spanish rabbi and recognised leader of Jewry?
Ah, so..
Nachmanides
