Louis-Philippe was overthrown by a popular uprising in the streets of Paris in 1848. His successor, Napoleon III, and the newly appointed prefect of the Seine, Georges-Eugène Haussmann, launched a gigantic public works project to build wide new boulevards, a new opera house, a central market, new aqueducts, sewers, and parks, including the Bois de Boulogne and Bois de Vincennes. In 1860, Napoleon III also annexed the surrounding towns and created eight new arrondissements, expanding Paris to its current limits.
Who was Napoleon III's prefect of the Siene?

Textual criticism is a branch of textual scholarship, philology, and literary criticism that is concerned with the identification of textual variants in either manuscripts or printed books. Ancient scribes made alterations when copying manuscripts by hand. Given a manuscript copy, several or many copies, but not the original document, the textual critic might seek to reconstruct the original text (the archetype or autograph) as closely as possible. The same processes can be used to attempt to reconstruct intermediate versions, or recensions, of a document's transcription history. The ultimate objective of the textual critic's work is the production of a "critical edition" containing a scholarly curated text.
What type of edition does a textual critic usually analyze?
A: unanswerable

Currently, the rapid influx of northerners and immigrants from Latin America is steadily increasing ethnic and religious diversity: the number of Roman Catholics and Jews in the state has increased, as well as general religious diversity.

In particle physics, this inequality permits a qualitative understanding of virtual particles which carry momentum, exchange by which and with real particles, is responsible for the creation of all known fundamental forces (more accurately known as fundamental interactions). Virtual photons (which are simply lowest quantum mechanical energy state of photons) are also responsible for electrostatic interaction between electric charges (which results in Coulomb law), for spontaneous radiative decay of exited atomic and nuclear states, for the Casimir force, for van der Waals bond forces and some other observable phenomena.
What are simply highest quantum mechanical energy state of photons?
A:
unanswerable
