In 1978, Queen toured the US and Canada, and spent much of 1979 touring in Europe and Japan. They released their first live album, Live Killers, in 1979; it went platinum twice in the US. Queen also released the very successful single "Crazy Little Thing Called Love", a rockabilly inspired song done in the style of Elvis Presley. The song made the top 10 in many countries, topped the Australian ARIA Charts for seven consecutive weeks, and was the band's first number one single in the United States where it topped the Billboard Hot 100 for four weeks. Having written the song on guitar and played rhythm on the record, Mercury played rhythm guitar while performing the song live, which was the first time he ever played guitar in concert. In December 1979, Queen played the opening night at the Concert for the People of Kampuchea in London, having accepted a request by the event's organiser Paul McCartney.

Problem: Please answer a question about the following article about Airport:
Hazards to aircraft include debris, nesting birds, and reduced friction levels due to environmental conditions such as ice, snow, or rain. Part of runway maintenance is airfield rubber removal which helps maintain friction levels. The fields must be kept clear of debris using cleaning equipment so that loose material does not become a projectile and enter an engine duct (see foreign object damage). In adverse weather conditions, ice and snow clearing equipment can be used to improve traction on the landing strip. For waiting aircraft, equipment is used to spray special deicing fluids on the wings.
In adverse weather conditions, what can be used to improve traction on the landing strip?
A: ice and snow clearing equipment

The Early Cretaceous spans from 145 million to 100 million years ago. The Early Cretaceous saw the expansion of seaways, and as a result, the decline and extinction of sauropods (except in South America). Many coastal shallows were created, and that caused Ichthyosaurs to die out. Mosasaurs evolved to replace them as head of the seas. Some island-hopping dinosaurs, like Eustreptospondylus, evolved to cope with the coastal shallows and small islands of ancient Europe. Other dinosaurs rose up to fill the empty space that the Jurassic-Cretaceous extinction left behind, such as Carcharodontosaurus and Spinosaurus. Of the most successful would be the Iguanodon which spread to every continent. Seasons came back into effect and the poles got seasonally colder, but dinosaurs still inhabited this area like the Leaellynasaura which inhabited the polar forests year-round, and many dinosaurs migrated there during summer like Muttaburrasaurus. Since it was too cold for crocodiles, it was the last stronghold for large amphibians, like Koolasuchus. Pterosaurs got larger as species like Tapejara and Ornithocheirus evolved.

What event of the Early Cretaceous caused the extinction of several species?
Answer: expansion of seaways

Problem: Further firefights between Armenian militiamen and Soviet troops occurred in Sovetashen, near the capital and resulted in the deaths of over 26 people, mostly Armenians. The pogrom of Armenians in Baku in January 1990 forced almost all of the 200,000 Armenians in the Azerbaijani capital Baku to flee to Armenia. On 17 March 1991, Armenia, along with the Baltic states, Georgia and Moldova, boycotted a nationwide referendum in which 78% of all voters voted for the retention of the Soviet Union in a reformed form.
Continued fighting transpired between the Armenians and Soviets in which city?
The answer is the following: Sovetashen

On December 13, 2013, Beyonce unexpectedly released her eponymous fifth studio album on the iTunes Store without any prior announcement or promotion.

In April 2014, after much speculation in the weeks before, Beyonce and Jay Z officially announced their On the Run Tour. It served as the couple's first co-headlining stadium tour together.

Here is a question about this article: In the spring of 1834, Chopin attended the Lower Rhenish Music Festival in Aix-la-Chapelle with Hiller, and it was there that Chopin met Felix Mendelssohn. After the festival, the three visited Dusseldorf, where Mendelssohn had been appointed musical director. They spent what Mendelssohn described as "a very agreeable day", playing and discussing music at his piano, and met Friedrich Wilhelm Schadow, director of the Academy of Art, and some of his eminent pupils such as Lessing, Bendemann, Hildebrandt and Sohn. In 1835 Chopin went to Carlsbad, where he spent time with his parents; it was the last time he would see them. On his way back to Paris, he met old friends from Warsaw, the Wodzinskis. He had made the acquaintance of their daughter Maria in Poland five years earlier, when she was eleven. This meeting prompted him to stay for two weeks in Dresden, when he had previously intended to return to Paris via Leipzig. The sixteen-year-old girl's portrait of the composer is considered, along with Delacroix's, as among Chopin's best likenesses. In October he finally reached Leipzig, where he met Schumann, Clara Wieck and Felix Mendelssohn, who organised for him a performance of his own oratorio St. Paul, and who considered him "a perfect musician". In July 1836 Chopin travelled to Marienbad and Dresden to be with the Wodzinski family, and in September he proposed to Maria, whose mother Countess Wodzinska approved in principle. Chopin went on to Leipzig, where he presented Schumann with his G minor Ballade. At the end of 1836 he sent Maria an album in which his sister Ludwika had inscribed seven of his songs, and his 1835 Nocturne in C-sharp minor, Op. 27, No. 1. The anodyne thanks he received from Maria proved to be the last letter he was to have from her.
What is the answer to this question: Who did Chopin attend the Lower Rhenish Music Festival with?
****
So...
Hiller
