[EX Q]: Question: Why did de Angeli choose the names she did for her characters in her first book? Passage 1:The Tremp Basin evolved into a sedimentary depression with the break-up of Pangea and the spreading of the North American and Eurasian Plates in the Early Jurassic. Rifting between Africa and Europe in the Early Cretaceous created the isolated Iberian microplate, where the Tremp Basin was located in the northeastern corner in a back-arc basin tectonic regime. Between the middle Albian and early Cenomanian, a series of pull-apart basins developed, producing a local unconformity in the Tremp Basin. A first phase of tectonic compression commenced in the Cenomanian, lasting until the late Santonian, around 85 Ma, when Iberia started to rotate counterclockwise towards Europe, producing a series of piggyback basins in the southern Pre-Pyrenees. A more tectonically quiet posterior phase provided the Tremp Basin with a shallowing-upward sequence of marine carbonates until the moment of deposition of the Tremp Formation, in the lower section still marginally marine, but becoming more continental and lagoonal towards the top.
 Passage 2:In 1961, Sadegh Tabatabai went to Aachen to study biochemistry and later received his doctorate from the University of Bochum. While in Aachen, he organized a student group that campaigned against Shah Mohammad Reza Pahlavi. In 1967, he handled Ulrike Meinhof material about Iran, which was used in a famous column in Konkret magazine opposing the Shah's visit to West Germany that year. Tabatabai gave a speech at the grave of Benno Ohnesorg, an unarmed university student who was shot during a demonstration against the Shah's visit to the Deutsche Oper in Berlin by Karl-Heinz Kurras, a police officer later discovered to be an agent of the East German secret police, the Stasi.

The first of their six children, John Shadrach de Angeli, was born one year later. After living in many locations in the American and Canadian West, they settled in the Philadelphia suburb of Collingswood, New Jersey. There in 1921 Marguerite started to study drawing under her mentor, Maurice Bower. In 1922, Marguerite began illustrating a Sunday School paper and was soon doing illustrations for magazines such as The Country Gentleman, Ladies' Home Journal, and The American Girl, besides illustrating books for authors including Helen Ferris, Elsie Singmaster, Cornelia Meigs, and Dorothy Canfield Fisher. Her last child, Maurice Bower de Angeli, was born in 1928, seven years before the 1935 publication of her first book, Ted and Nina Go to the Grocery Store. The de Angeli family moved frequently, returning to Pennsylvania and living north of Philadelphia in Jenkintown, west of Philadelphia in the Manoa neighborhood of Havertown, on Carpenter Lane in Germantown, Philadelphia, on Panama Street in Center City, Philadelphia, in an apartment near the Philadelphia Art Museum, and in a cottage in Green Lane, Pennsylvania. They also maintained a summer cabin on Money Island in Toms River, New Jersey. Marguerite's husband died in 1969, eight months before their 60th wedding anniversary.

 Passage 2:Initially a supporter of the Swiss fascist movement of Arthur Fonjallaz, he came to wider attention in 1949 when he published Ubu Justicier au Premier Procès de Nuremberg, one of the first works to question the veracity of the Holocaust. Increasingly active in neo-fascism, he organized conferences in Malmö in 1951 which led to the formation of a pan-European nationalist group known as the European Social Movement and then led the more radical splinter group known as the New European Order later that year. This group sought the creation of a new Rome–Berlin axis to unite Europe against capitalism and communism and in January 1953 set up a European Liaison Office under Amaudruz in Lausanne to co-ordinate the work of affiliated groups. He also came an early member of the Volkspartei der Schweiz but left the party over the issue of South Tyrol (where he was opposed to irredentism). Of all the groups involved Amaudruz was closest to Ordine Nuovo. Conferences were held irregularly, although membership was fluid and Amaudruz devoted much of his time to writing for journals such as Nation Europa.
