Problem: Like all the Romance languages, Catalan verbal inflection is more complex than the nominal. Suffixation is omnipresent, whereas morphological alternations play a secondary role. Vowel alternances are active, as well as infixation and suppletion. However, these are not as productive as in Spanish, and are mostly restricted to irregular verbs.
What plays a secondary part in Catalan?

Answer: morphological alternations

Context and question: New Haven's greatest culinary claim to fame may be its pizza, which has been claimed to be among the best in the country, or even in the world. New Haven-style pizza, called "apizza" (pronounced ah-BEETS, [apitts] in the original Italian dialect), made its debut at the iconic Frank Pepe Pizzeria Napoletana (known as Pepe's) in 1925. Apizza is baked in coal- or wood-fired brick ovens, and is notable for its thin crust. Apizza may be red (with a tomato-based sauce) or white (with a sauce of garlic and olive oil), and pies ordered "plain" are made without the otherwise customary mozzarella cheese (originally smoked mozzarella, known as "scamorza" in Italian). A white clam pie is a well-known specialty of the restaurants on Wooster Street in the Little Italy section of New Haven, including Pepe's and Sally's Apizza (which opened in 1938). Modern Apizza on State Street, which opened in 1934, is also well-known.
In general what are "apizza" known for?
Answer: its thin crust

Question: The old oracles in Delphi seem to be connected with a local tradition of the priesthood, and there is not clear evidence that a kind of inspiration-prophecy existed in the temple. This led some scholars to the conclusion that Pythia carried on the rituals in a consistent procedure through many centuries, according to the local tradition. In that regard, the mythical seeress Sibyl of Anatolian origin, with her ecstatic art, looks unrelated to the oracle itself. However, the Greek tradition is referring to the existence of vapours and chewing of laurel-leaves, which seem to be confirmed by recent studies.
Is there an answer to this question: Who did scholars beieve carried on the rituals in a consistent procedure?

Answer: Pythia

Question: 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)
Is there an answer to this question: Why is Chan suing the Hong Kong government?

Answer:
her human rights were breached.
