Article: One of the few city states who managed to maintain full independence from the control of any Hellenistic kingdom was Rhodes. With a skilled navy to protect its trade fleets from pirates and an ideal strategic position covering the routes from the east into the Aegean, Rhodes prospered during the Hellenistic period. It became a center of culture and commerce, its coins were widely circulated and its philosophical schools became one of the best in the mediterranean. After holding out for one year under siege by Demetrius Poliorcetes (304-305 BCE), the Rhodians built the Colossus of Rhodes to commemorate their victory. They retained their independence by the maintenance of a powerful navy, by maintaining a carefully neutral posture and acting to preserve the balance of power between the major Hellenistic kingdoms.

Question: What did Rhodians build to commemorate their victory over Demetrius Poliorcetes?
Ans: Colossus of Rhodes

Here is a question about this article: There were several protests along the torch relay route. Members of the Hong Kong Alliance in Support of Patriotic Democratic Movements in China, including pro-democracy activist Szeto Wah, waved novelty inflatable plastic Olympic flames, which they said symbolised democracy. They wanted accountability for the Tiananmen Square protests of 1989 and the implementation of democracy in Hong Kong. Political activist and Legislative Council member Leung Kwok-hung (Longhair) also joined the protest, saying "I'm very proud that in Hong Kong we still have people brave enough to speak out." Pro-democracy activists were overwhelmed by a crowd of torch supporters with insults like "running dog," "traitor," "get out!," and "I love the Communist Party." At the same time, about 10 members of the Civil Human Rights Front had orange banners calling for human rights improvements and universal suffrage. Onlookers were saying "Aren't you Chinese?" in Mandarin putonghua as they tried to cover the orange banners with a large Chinese national flag. One woman had an orange sign that said, "Olympic flame for democracy", while a man carried a poster with a tank and the slogan "One world, two dreams". A university student and former RDHK radio host Christina Chan wrapped the Tibetan snow lion flag around her body and later began waving it. Several onlookers heckled Chan, shouting "What kind of Chinese are you?" and "What a shame!" In the end, she and some of the protesters were taken away against their will by the authorities via a police vehicle "for their own protection." Chan is currently[when?] suing the Hong Kong government, claiming her human rights were breached. (case number HCAL139/08)
What is the answer to this question: Why is Chan suing the Hong Kong government?
****
So... her human rights were breached.

The problem: Answer a question about this article:
Delicate sounds and fine overtones were mostly lost, because it took a lot of sound energy to vibrate the recording horn diaphragm and cutting mechanism. There were acoustic limitations due to mechanical resonances in both the recording and playback system. Some pictures of acoustic recording sessions show horns wrapped with tape to help mute these resonances. Even an acoustic recording played back electrically on modern equipment sounds like it was recorded through a horn, notwithstanding a reduction in distortion because of the modern playback. Toward the end of the acoustic era, there were many fine examples of recordings made with horns.
Why do photos show take on horns?
****
The answer: help mute these resonances

Problem: Please answer a question about the following article about Renewable energy commercialization:
The PV industry has seen drops in module prices since 2008. In late 2011, factory-gate prices for crystalline-silicon photovoltaic modules dropped below the $1.00/W mark. The $1.00/W installed cost, is often regarded in the PV industry as marking the achievement of grid parity for PV. These reductions have taken many stakeholders, including industry analysts, by surprise, and perceptions of current solar power economics often lags behind reality. Some stakeholders still have the perspective that solar PV remains too costly on an unsubsidized basis to compete with conventional generation options. Yet technological advancements, manufacturing process improvements, and industry re-structuring, mean that further price reductions are likely in coming years.
What is a sign that further price reductions are likely in coming years?
A: technological advancements

Kanye West began his early production career in the mid-1990s, making beats primarily for burgeoning local artists, eventually developing a style that involved speeding up vocal samples from classic soul records. His first official production credits came at the age of nineteen when he produced eight tracks on Down to Earth, the 1996 debut album of a Chicago rapper named Grav. For a time, West acted as a ghost producer for Deric "D-Dot" Angelettie. Because of his association with D-Dot, West wasn't able to release a solo album, so he formed and became a member and producer of the Go-Getters, a late-1990s Chicago rap group composed of him, GLC, Timmy G, Really Doe, and Arrowstar. His group was managed by John "Monopoly" Johnson, Don Crowley, and Happy Lewis under the management firm Hustle Period. After attending a series of promotional photo shoots and making some radio appearances, The Go-Getters released their first and only studio album World Record Holders in 1999. The album featured other Chicago-based rappers such as Rhymefest, Mikkey Halsted, Miss Criss, and Shayla G. Meanwhile, the production was handled by West, Arrowstar, Boogz, and Brian "All Day" Miller.

What late 1990s Chicago rap group was Kanye West a member of?
Answer: Go-Getters

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."
What year was "Ray of Light" released?
1998
