Problem: Dutch language:

Like most Germanic languages, Dutch forms noun compounds, where the first noun modifies the category given by the second (hondenhok = doghouse). Unlike English, where newer compounds or combinations of longer nouns are often written in open form with separating spaces, Dutch (like the other Germanic languages) either uses the closed form without spaces (boomhuis = tree house) or inserts a hyphen (VVD-coryfee = outstanding member of the VVD, a political party). Like German, Dutch allows arbitrarily long compounds, but the longer they get, the less frequent they tend to be.

What language is like Dutch in allowing compounds to be any length?

A: German

By the end of the month, the Peloponnese was in open revolt against the Ottomans and by October 1821 the Greeks under Theodoros Kolokotronis had captured Tripolitsa. The Peloponnesian revolt was quickly followed by revolts in Crete, Macedonia and Central Greece, which would soon be suppressed. Meanwhile, the makeshift Greek navy was achieving success against the Ottoman navy in the Aegean Sea and prevented Ottoman reinforcements from arriving by sea. In 1822 and 1824 the Turks and Egyptians ravaged the islands, including Chios and Psara, committing wholesale massacres of the population. This had the effect of galvanizing public opinion in western Europe in favor of the Greek rebels.[page needed]
The Greek and Ottoman Navy fought in which waters?

Question: On August 17, 2007, Dell Inc. announced that after an internal investigation into its accounting practices it would restate and reduce earnings from 2003 through to the first quarter of 2007 by a total amount of between $50 million and $150 million, or 2 cents to 7 cents per share.
