Problem: From the second half of the 20th century on parties which continued to rely on donations or membership subscriptions ran into mounting problems. Along with the increased scrutiny of donations there has been a long-term decline in party memberships in most western democracies which itself places more strains on funding. For example, in the United Kingdom and Australia membership of the two main parties in 2006 is less than an 1/8 of what it was in 1950, despite significant increases in population over that period.
What was the population of Australia in the 20th century compared to 1950?

Problem: 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."
What was Whitehead's wish upon his death for his family?
---
Answer: all of his papers be destroyed after his death.

Problem: The system displays the What's New screen by default instead of the [Games] menu (or [Video] menu, if a movie was inserted) when starting up. What's New has four sections: "Our Pick", "Recently Played", latest information and new content available in PlayStation Store. There are four kinds of content the What's New screen displays and links to, on the sections. "Recently Played" displays the user's recently played games and online services only, whereas, the other sections can contain website links, links to play videos and access to selected sections of the PlayStation Store.
What section of What's New would a user visit to find the games they've never played?
