Q: Passage: Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago.  Whales consist of eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), Eschrichtiidae (the grey whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm whale), Kogiidae (the dwarf and pygmy sperm whale), and Ziphiidae (the beaked whales).
Whales are creatures of the open ocean; they feed, mate, give birth, suckle and raise their young at sea. So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. The sperm whale is the largest toothed predator on earth. Several species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead they have plates of baleen, a fringe-like structure used to expel water while retaining the krill and plankton which they feed on. They use their throat pleats to expand the mouth to take in huge gulps of water. Balaenids have heads that can make up 40% of their body mass to take in water. Toothed whales, on the other hand, have conical teeth adapted to catching fish or squid. Baleen whales have a well developed sense of "smell", whereas toothed whales have well-developed hearing − their hearing, that is adapted for both air and water, is so well developed that some can survive even if they are blind. Some species, such as sperm whales, are well adapted for diving to great depths to catch squid and other favoured prey. 
Question: What are the types of whales that use throat pleats to expand the mouth?

A: Baleen.

Q: Passage: Ottavio's marriage troubled Alessandro; he struggled with the burden of chastity and entertained fantasies of marrying a princess. He resented his younger brother's arrangement; during the wedding ceremony he "became more deathly pale than death itself, and, so they say, is unable to bear this thing, that he, the first-born, should see himself deprived of such splendid status and of the daughter of an Emperor." In 1546 Paul gave Pier Luigi the duchies of Parma and Piacenza as papal fiefs, a highly political move by the pope: in doing so he gave titles and wealth to Pier and appointed a lord who was subservient and owed a debt of gratitude, guaranteeing that the duchies would remain under papal control. At the same time, Ottavio was posted to the North of Italy to support Charles. By 1546 Ottavio was 22 years old, married to Margaret of Austria and an accomplished and distinguished individual. In 1547 his father was assassinated and Ottavio claimed the dukedom of Parma and Piacenza against the express wishes of both Charles, his father-in-law, and Paul. In doing so, Ottavio acted in opposition to the pope's desire to maintain the duchies as papal fiefs, and to Charles, whom he believed responsible for the plot to assassinate Pier Luigi.Titian was a personal friend of Charles; the commissioning of the portrait was most likely intended by Paul as a signal of allegiance to the emperor. Pressure from reforming monarchs in France and Spain, coupled with a general shift of influence in France's favour, ended the Farnese hold on the papacy soon after Paul's death. Ottavio excelled as a military commander and was awarded the Golden Fleece by the emperor. While the post had been given as a means to strengthen the family position, it did not come without cost. His success bred resentment amongst his family, as he began to see himself unaccountable to Rome.At the time of the portrait Paul had convinced Alessandro to retain the post, hinting that he would later succeed him as pope – an aspiration that was ultimately frustrated. As Alessandro realised the emptiness of the promise he lost confidence in both his grandfather's word and political credibility. 
Question: What was the name of Alessandro's brother?

A: Ottavio.
