Question: What symptoms did Maria del Carmen likely experience before she died? Passage 1:In 1953 he was commissioned to the rank of sub lieutenant after completing basic training, after which he was elevated to the rank of lieutenant in 1955, and lieutenant commander in 1963. From 1969 to 1970 he was the defence attaché, at the Sri Lanka High Commission in London before being promoted to commander in November 1970, after which he was the commanding officer HMCyS Gajabahu the flagship of the fleet and the co-ordinating officer of the Polonnaruwa District during the 1971 Insurrection. He was the Naval Officer-in Charge of Trincomalee when he was promoted to the rank of captain in 1973, after which he was the Master of MV Lanka Kanthi of the Ceylon Shipping Corporation before becoming chief staff officer (operations). He went on to serve as the co-ordinating officer TAFII (East) and Director Naval Operations when on February 4, 1978, he was made commodore. On July 1, 1979, he assumed duties as the chief of staff at Naval Headquarters, SLNS Ranagala, after which he was promoted to the rank of rear admiral. In June 1983 he was made Commander of the navy, a post he would hold till his retirement at the age of 55, on 1 November 1986, at which point he became the first Sri Lankan officer to be elevated to the rank of vice admiral in the Sri Lanka Navy.

 Passage 2:Many young people in Canada at this time, especially young women, were influenced by the 1960s counterculture and identified with Trudeau, an energetic nonconformist who was relatively young. They were dazzled by his "charm and good looks", and a large fan base was established throughout the country. He would often be stopped in the streets for his autograph or for photographs. Trudeau had once sympathized with Marxists and had spent time in the democratic socialist Cooperative Commonwealth Federation, and many of his fans were attracted to his culturally liberal stances (he legalized homosexuality and created more flexible divorce laws as Justice Minister under Lester B. Pearson). Trudeau was also admired for his laid-back attitude and his celebrity relationships; in that word's prevailing use at the time, describing a modern, "hip and happening person", he was often described as a swinger. A high point happened during Trudeau's election campaign in 1968 during the annual Saint-Jean-Baptiste Day parade in Montreal, when rioting Quebec separatists threw rocks and bottles at the grandstand where Trudeau was seated. Rejecting the pleas of his aides that he take cover, Trudeau stayed in his seat, facing the rioters, without any sign of fear. The image of the politician showing such courage impressed the Canadian people, and he handily won the election the next day.
 Passage 3:The family later sought safety in San Sebastian and Mari Carmen was sent to a boarding school, School of the Reverend Irish Mothers of the Blessed Virgin Mary, in Zalla. She prayed for the conversion of the men who had killed her father. She offered up her own suffering and death for the conversion of politician Manuel Azaña. Supporters for her canonization say that Azaña was converted on his deathbed in 1940. After weeks of illness, Maria del Carmen died of scarlet fever at the age of nine years, four months. She had initially predicted she would die on July 16, the feast day of her patron saint, Our Lady of Mount Carmel, but when she learned her aunt would be married on that day, she said she would die on July 17, the following day. Her last words were reportedly "I die as a martyr. Please, doctor, let me go now. Don’t you see that the Blessed Virgin has come with the angels to get me?" and "Jesus, Mary, Joseph, may I breathe forth my soul with you." Witnesses at her death bed said her body emitted a sweet perfume and she did not look dead.
