Here is a question about this article: Following the 1973 war and the subsequent peace treaty, Egypt became the first Arab nation to establish diplomatic relations with Israel. Despite that, Israel is still widely considered as a hostile state by the majority of Egyptians. Egypt has played a historical role as a mediator in resolving various disputes in the Middle East, most notably its handling of the Israeli-Palestinian conflict and the peace process. Egypt's ceasefire and truce brokering efforts in Gaza have hardly been challenged following Israel's evacuation of its settlements from the strip in 2005, despite increasing animosity towards the Hamas government in Gaza following the ouster of Mohamed Morsi, and despite recent attempts by countries like Turkey and Qatar to take over this role.
What is the answer to this question: What country has Egypt famously had peace with since 1973 treaty?
****
So... Israel

The problem: Answer a question about this article:
Bacteria were first observed by the Dutch microscopist Antonie van Leeuwenhoek in 1676, using a single-lens microscope of his own design. He then published his observations in a series of letters to the Royal Society of London. Bacteria were Leeuwenhoek's most remarkable microscopic discovery. They were just at the limit of what his simple lenses could make out and, in one of the most striking hiatuses in the history of science, no one else would see them again for over a century. Only then were his by-then-largely-forgotten observations of bacteria as opposed to his famous "animalcules" (spermatozoa) taken seriously.
Who discovered bacteria?
****
The answer: Dutch microscopist Antonie van Leeuwenhoek

The Gold Standard Act of 1900 abandoned the bimetallic standard and defined the dollar as 23.22 grains (1.505 g) of gold, equivalent to setting the price of 1 troy ounce of gold at $20.67. Silver coins continued to be issued for circulation until 1964, when all silver was removed from dimes and quarters, and the half dollar was reduced to 40% silver.
