Question: In 2007, RIBA called for minimum space standards in newly built British houses after research was published suggesting that British houses were falling behind other European countries. "The average new home sold to people today is significantly smaller than that built in the 1920s... We're way behind the rest of Europe—even densely populated Holland has better proportioned houses than are being built in the country. So let's see minimum space standards for all new homes," said RIBA president Jack Pringle.
Is there an answer to this question: What decade did Pringle favorably compare the size of modern British homes?

Answer: unanswerable


Question: Videophone calls (also: videocalls, video chat as well as Skype and Skyping in verb form), differ from videoconferencing in that they expect to serve individuals, not groups. However that distinction has become increasingly blurred with technology improvements such as increased bandwidth and sophisticated software clients that can allow for multiple parties on a call. In general everyday usage the term videoconferencing is now frequently used instead of videocall for point-to-point calls between two units. Both videophone calls and videoconferencing are also now commonly referred to as a video link.
Is there an answer to this question: How does increased bandwidth differ from point-to-point calls?

Answer:
unanswerable
