Here is a question about this article: Between the German invasion of Poland on 1 September 1939 and the Anglo-French declaration of War against the German Reich on 3 September 1939, the entire city (a total of 120,000 people) was evacuated, like other border towns as well. Until the arrival of the Wehrmacht troops mid-June 1940, the city was, for ten months, completely empty, with the exception of the garrisoned soldiers. The Jews of Strasbourg had been evacuated to Perigueux and Limoges, the University had been evacuated to Clermont-Ferrand.
What is the answer to this question: How many people were evacuated during the invasion?
****
So... 120,000

Here is a question about this article: When a Teletype 33 ASR equipped with the automatic paper tape reader received a Control-S (XOFF, an abbreviation for transmit off), it caused the tape reader to stop; receiving Control-Q (XON, "transmit on") caused the tape reader to resume. This technique became adopted by several early computer operating systems as a "handshaking" signal warning a sender to stop transmission because of impending overflow; it persists to this day in many systems as a manual output control technique. On some systems Control-S retains its meaning but Control-Q is replaced by a second Control-S to resume output. The 33 ASR also could be configured to employ Control-R (DC2) and Control-T (DC4) to start and stop the tape punch; on some units equipped with this function, the corresponding control character lettering on the keycap above the letter was TAPE and TAPE respectively.
What is the answer to this question: What was the warning signal called that warned the sender that there was impending overflow?
****
So... handshaking

Here is a question about this article: While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps.
What is the answer to this question: What affects the thermal conductivity of a gas?
****
So...
molecular weight of the gas and the cross sectional area of the gas molecules
