Problem: Database:

The final stage of database design is to make the decisions that affect performance, scalability, recovery, security, and the like. This is often called physical database design. A key goal during this stage is data independence, meaning that the decisions made for performance optimization purposes should be invisible to end-users and applications. Physical design is driven mainly by performance requirements, and requires a good knowledge of the expected workload and access patterns, and a deep understanding of the features offered by the chosen DBMS.

What requires no knowledge of the expected workload?

Problem: Israel:

Temperatures in Israel vary widely, especially during the winter. Coastal areas, such as those of Tel Aviv and Haifa, have a typical Mediterranean climate with cool, rainy winters and long, hot summers. The area of Beersheba and the Northern Negev has a semi-arid climate with hot summers, cool winters and fewer rainy days than the Mediterranean climate. The Southern Negev and the Arava areas have desert climate with very hot and dry summers, and mild winters with few days of rain. The highest temperature in the continent of Asia (54.0 °C or 129.2 °F) was recorded in 1942 at Tirat Zvi kibbutz in the northern Jordan river valley.

What kind of climate does Arava have?

Problem: East India Company:

During the period of the Napoleonic Wars, the East India Company arranged for letters of marque for its vessels such as the Lord Nelson. This was not so that they could carry cannon to fend off warships, privateers and pirates on their voyages to India and China (that they could do without permission) but so that, should they have the opportunity to take a prize, they could do so without being guilty of piracy. Similarly, the Earl of Mornington, an East India Company packet ship of only six guns, also sailed under a letter of marque.

How many guns were taken from the Earl of Mornington?
---
A: unanswerable


Problem: Hanover:

"Hanover" is the traditional English spelling. The German spelling (with a double n) is becoming more popular in English; recent editions of encyclopedias prefer the German spelling, and the local government uses the German spelling on English websites. The English pronunciation /ˈhænəvər/, with stress on the first syllable and a reduced second syllable, is applied to both the German and English spellings, which is different from German pronunciation [haˈnoːfɐ], with stress on the second syllable and a long second vowel. The traditional English spelling is still used in historical contexts, especially when referring to the British House of Hanover.

What does the German spelling of Hanover have that English does not?

A:
a double n
