Approximately 250,000 United States troops, with support from 45,000 British, 2,000 Australian and 200 Polish combat forces, entered Iraq primarily through their staging area in Kuwait.

After approximately three weeks of fighting, Hussein and the Ba'ath Party were forcibly removed, followed by 9 years of military presence by the United States and the coalition fighting alongside the newly elected Iraqi government against various insurgent groups.

Problem: Extract the answer to the question from the following context. Question: What is the most common name for the planet Neptune? Context: Most languages today, even in countries that have no direct link to Greco-Roman culture, use some variant of the name "Neptune" for the planet. However, in Chinese, Japanese, and Korean, the planet's name was translated as "sea king star" (), because Neptune was the god of the sea. In Mongolian, Neptune is called Dalain Van ( ), reflecting its namesake god's role as the ruler of the sea. In modern Greek the planet is called Poseidon (, Poseidonas), the Greek counterpart of Neptune. In Hebrew, "Rahab" (), from a Biblical sea monster mentioned in the Book of Psalms, was selected in a vote managed by the Academy of the Hebrew Language in 2009 as the official name for the planet, even though the existing Latin term "Neptun" () is commonly used. In Maori, the planet is called Tangaroa, named after the Maori god of the sea. In Nahuatl, the planet is called Tlaloccitlalli, named after the rain god Tlaloc.

Problem: Extract the answer to the question from the following context. Question: What was Ray of light? Context: Madonna's seventh studio album, Ray of Light, (1998) reflected a change in her image. She collaborated with electronica producer William Orbit and wanted to create a sound that could blend dance music with pop and British rock. American music critic Ann Powers explained that what Madonna searched for with Orbit "was a kind of a lushness that she wanted for this record. Techno and rave was happening in the 90's and had a lot of different forms. There was very experimental, more hard stuff like Aphex Twin. There was party stuff like Fatboy Slim. That's not what Madonna wanted for this. She wanted something more like a singer-songwriter, really. And William Orbit provided her with that."
