How bad were Nasser's heart attacks?, Context: Nasser had few personal vices other than chain smoking. He maintained 18-hour workdays and rarely took time off for vacations. The combination of smoking and working long hours contributed to his poor health. He was diagnosed with diabetes in the early 1960s and by the time of his death in 1970, he also had arteriosclerosis, heart disease, and high blood pressure. He suffered two major heart attacks (in 1966 and 1969), and was on bed rest for six weeks after the second episode. State media reported that Nasser's absence from the public view at that time was a result of influenza.

What posthumous service did Lowe perform on Whitehead's behalf?, Context: The two volume biography of Whitehead by Victor Lowe is the most definitive presentation of the life of Whitehead. However, many details of Whitehead's life remain obscure because he left no Nachlass; his family carried out his instructions that all of his papers be destroyed after his death. Additionally, Whitehead was known for his "almost fanatical belief in the right to privacy", and for writing very few personal letters of the kind that would help to gain insight on his life. This led to Lowe himself remarking on the first page of Whitehead's biography, "No professional biographer in his right mind would touch him."

Who is the claimant?, Context: It criticised Forsyth's decision to record a conversation with Harry as an abuse of teacher–student confidentiality and said "It is clear whichever version of the evidence is accepted that Mr Burke did ask the claimant to assist Prince Harry with text for his expressive art project ... It is not part of this tribunal's function to determine whether or not it was legitimate." In response to the tribunal's ruling concerning the allegations about Prince Harry, the School issued a statement, saying Forsyth's claims "were dismissed for what they always have been - unfounded and irrelevant." A spokesperson from Clarence House said, "We are delighted that Harry has been totally cleared of cheating."
