Problem: Neoclassical architecture:

The first phase of neoclassicism in France is expressed in the "Louis XVI style" of architects like Ange-Jacques Gabriel (Petit Trianon, 176268); the second phase, in the styles called Directoire and "Empire", might be characterized by Jean Chalgrin's severe astylar Arc de Triomphe (designed in 1806). In England the two phases might be characterized first by the structures of Robert Adam, the second by those of Sir John Soane. The interior style in France was initially a Parisian style, the "Gout grec" ("Greek style") not a court style. Only when the young king acceded to the throne in 1771 did Marie Antoinette, his fashion-loving Queen, bring the "Louis XVI" style to court.

France's second phase of neoclassic is known as what?
---
A: Directoire and "Empire"

Problem: Christian:

In Arabic-speaking cultures, two words are commonly used for Christians: Nasrani (), plural Nasara () is generally understood to be derived from Nazareth through the Syriac (Aramaic); Masihi () means followers of the Messiah. The term Nasara rose to prominence in July 2014, after the Fall of Mosul to the terrorist organization Islamic State of Iraq and the Levant. The nun or the first letter of Nasarawas spray-painted on the property of Christians ejected from the city.

What was spray pained on the properties of Christians who left the area?
---
A: the first letter of Nasara

Problem: Data compression:

Lossless audio compression produces a representation of digital data that decompress to an exact digital duplicate of the original audio stream, unlike playback from lossy compression techniques such as Vorbis and MP3. Compression ratios are around 5060% of original size, which is similar to those for generic lossless data compression. Lossless compression is unable to attain high compression ratios due to the complexity of waveforms and the rapid changes in sound forms. Codecs like FLAC, Shorten and TTA use linear prediction to estimate the spectrum of the signal. Many of these algorithms use convolution with the filter [-1 1] to slightly whiten or flatten the spectrum, thereby allowing traditional lossless compression to work more efficiently. The process is reversed upon decompression.

What are around 50-60% of the original size?
---
A: Compression ratios

Problem: Botany:

Epigenetic changes in eukaryotic biology serve to regulate the process of cellular differentiation. During morphogenesis, totipotent stem cells become the various pluripotent cell lines of the embryo, which in turn become fully differentiated cells. A single fertilized egg cell, the zygote, gives rise to the many different plant cell types including parenchyma, xylem vessel elements, phloem sieve tubes, guard cells of the epidermis, etc. as it continues to divide. The process results from the epigenetic activation of some genes and inhibition of others.

What process causes changes in plant cells?
---
A:
Epigenetic changes
