Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Simultaneous videoconferencing among three or more remote points is possible by means of a Multipoint Control Unit (MCU). This is a bridge that interconnects calls from several sources (in a similar way to the audio conference call). All parties call the MCU, or the MCU can also call the parties which are going to participate, in sequence. There are MCU bridges for IP and ISDN-based videoconferencing. There are MCUs which are pure software, and others which are a combination of hardware and software. An MCU is characterised according to the number of simultaneous calls it can handle, its ability to conduct transposing of data rates and protocols, and features such as Continuous Presence, in which multiple parties can be seen on-screen at once. MCUs can be stand-alone hardware devices, or they can be embedded into dedicated videoconferencing units.
What are remote points made of?
A: unanswerable

Context and question: Another theory describes its derivation from a non-Slavic warrior class,:42, 6466 forming a distinct element known as the Lechici/Lekhi (Lechitow):430 :482 within the ancient Polonic tribal groupings (Indo-European caste systems). This hypothesis states this upper class was not of Slavonic extraction:482 and was of a different origin than the Slavonic peasants (kmiecie; Latin: cmethones):430 :118 over which they ruled.:482 The Szlachta were differentiated from the rural population. The nobleman's sense of distinction led to practices that in later periods would be characterized as racism.:233 The Szlachta were noble in the Aryan sense -- "noble" in contrast to the people over whom they ruled after coming into contact with them.:482 The szlachta traced their descent from Lech/Lekh, who probably founded the Polish kingdom in about the fifth century.:482 Lechia was the name of Poland in antiquity, and the szlachta's own name for themselves was Lechici/Lekhi.:482 An exact counterpart of Szlachta society was the Meerassee system of tenure of southern Indiaan aristocracy of equalitysettled as conquerors among a separate race.:484 The Polish state paralleled the Roman Empire in that full rights of citizenship were limited to the szlachta. The szlachta were a caste, a military caste, as in Hindu society.
Who shares the same caste system as Hindu?
Answer: The szlachta

In 1997, a year after the divorce, Diana was killed in a car crash in Paris. The Queen was on holiday with her extended family at Balmoral. Diana's two sons by CharlesPrinces William and Harrywanted to attend church and so the Queen and Prince Philip took them that morning. After that single public appearance, for five days the Queen and the Duke shielded their grandsons from the intense press interest by keeping them at Balmoral where they could grieve in private, but the royal family's seclusion and the failure to fly a flag at half-mast over Buckingham Palace caused public dismay. Pressured by the hostile reaction, the Queen agreed to return to London and do a live television broadcast on 5 September, the day before Diana's funeral. In the broadcast, she expressed admiration for Diana and her feelings "as a grandmother" for the two princes. As a result, much of the public hostility evaporated.
When did Diana die?
A:
1997
