IR data transmission is also employed in short-range communication among computer peripherals and personal digital assistants. These devices usually conform to standards published by IrDA, the Infrared Data Association. Remote controls and IrDA devices use infrared light-emitting diodes (LEDs) to emit infrared radiation that is focused by a plastic lens into a narrow beam. The beam is modulated, i.e. switched on and off, to encode the data. The receiver uses a silicon photodiode to convert the infrared radiation to an electric current. It responds only to the rapidly pulsing signal created by the transmitter, and filters out slowly changing infrared radiation from ambient light. Infrared communications are useful for indoor use in areas of high population density. IR does not penetrate walls and so does not interfere with other devices in adjoining rooms. Infrared is the most common way for remote controls to command appliances. Infrared remote control protocols like RC-5, SIRC, are used to communicate with infrared.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What infrared remote control protocols are used in areas of high population density?
Ah, so.. unanswerable

Until the death of Sigismund II Augustus, the last king of the Jagiellonian dynasty, monarchs could be elected from within only the royal family. However, starting from 1573, practically any Polish noble or foreigner of royal blood could become a PolishLithuanian monarch. Every newly elected king was supposed to sign two documentsthe Pacta conventa ("agreed pacts")a confirmation of the king's pre-election promises, and Henrican articles (artykuy henrykowskie, named after the first freely elected king, Henry of Valois). The latter document served as a virtual Polish constitution and contained the basic laws of the Commonwealth:

Ah, so.. monarchs could be elected from within only the royal family

Luke's gospel also describes an interaction between Jesus and the women among the crowd of mourners following him, quoting Jesus as saying "Daughters of Jerusalem, do not weep for me, but weep for yourselves and for your children. For behold, the days are coming when they will say, 'Blessed are the barren and the wombs that never bore and the breasts that never nursed!' Then they will begin to say to the mountains, 'Fall on us,' and to the hills, 'Cover us.' For if they do these things when the wood is green, what will happen when it is dry?"[Lk. 23:28-31]
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did the women gather to keep themselves warm?
Ah, so..
unanswerable
