Input: Film speed
The ISO standard ISO 12232:2006 gives digital still camera manufacturers a choice of five different techniques for determining the exposure index rating at each sensitivity setting provided by a particular camera model. Three of the techniques in ISO 12232:2006 are carried over from the 1998 version of the standard, while two new techniques allowing for measurement of JPEG output files are introduced from CIPA DC-004. Depending on the technique selected, the exposure index rating can depend on the sensor sensitivity, the sensor noise, and the appearance of the resulting image. The standard specifies the measurement of light sensitivity of the entire digital camera system and not of individual components such as digital sensors, although Kodak has reported using a variation to characterize the sensitivity of two of their sensors in 2001.

What factors affect the exposure index rating?
Output: the sensor sensitivity, the sensor noise, and the appearance of the resulting image


Input: Article: The dynasty lost control of peripheral territories bit by bit. In return for promises of support against the British and the French, the Russian Empire took large chunks of territory in the Northeast in 1860. The period of cooperation between the reformers and the European powers ended with the Tientsin Massacre of 1870, which was incited by the murder of French nuns set off by the belligerence of local French diplomats. Starting with the Cochinchina Campaign in 1858, France expanded control of Indochina. By 1883, France was in full control of the region and had reached the Chinese border. The Sino-French War began with a surprise attack by the French on the Chinese southern fleet at Fuzhou. After that the Chinese declared war on the French. A French invasion of Taiwan was halted and the French were defeated on land in Tonkin at the Battle of Bang Bo. However Japan threatened to enter the war against China due to the Gapsin Coup and China chose to end the war with negotiations. The war ended in 1885 with the Treaty of Tientsin (1885) and the Chinese recognition of the French protectorate in Vietnam.

Now answer this question: When was the Tientsin Massacre?

Output: 1870


Article: However, in order to manage the tensions present in the Spanish transition to democracy, the drafters of the current Spanish constitution avoided giving labels such as 'federal' to the territorial arrangements. Besides, unlike in the federal system, the main taxes are taken centrally from Madrid (except for the Basque Country and Navarre, which were recognized in the Spanish democratic constitution as charter territories drawing from historical reasons) and then distributed to the Autonomous Communities.

Question: Where are the main taxes taken?
Ans: Madrid


Here is a question about this article: Compression efficiency of encoders is typically defined by the bit rate, because compression ratio depends on the bit depth and sampling rate of the input signal. Nevertheless, compression ratios are often published. They may use the Compact Disc (CD) parameters as references (44.1 kHz, 2 channels at 16 bits per channel or 2×16 bit), or sometimes the Digital Audio Tape (DAT) SP parameters (48 kHz, 2×16 bit). Compression ratios with this latter reference are higher, which demonstrates the problem with use of the term compression ratio for lossy encoders.
What is the answer to this question: What can CD parameters be used as references for?
****
So... compression ratios

With the automobile being the primary means of transportation for over 80 percent of its residents, San Diego is served by a network of freeways and highways. This includes Interstate 5, which runs south to Tijuana and north to Los Angeles; Interstate 8, which runs east to Imperial County and the Arizona Sun Corridor; Interstate 15, which runs northeast through the Inland Empire to Las Vegas and Salt Lake City; and Interstate 805, which splits from I-5 near the Mexican border and rejoins I-5 at Sorrento Valley.
Where does Interstate 805 split from I-5?
****
The answer: near the Mexican border

Plant circadian rhythms tell the plant what season it is and when to flower for the best chance of attracting pollinators. Behaviors showing rhythms include leaf movement, growth, germination, stomatal/gas exchange, enzyme activity, photosynthetic activity, and fragrance emission, among others. Circadian rhythms occur as a plant entrains to synchronize with the light cycle of its surrounding environment. These rhythms are endogenously generated and self-sustaining and are relatively constant over a range of ambient temperatures. Important features include two interacting transcription-translation feedback loops: proteins containing PAS domains, which facilitate protein-protein interactions; and several photoreceptors that fine-tune the clock to different light conditions. Anticipation of changes in the environment allows appropriate changes in a plant's physiological state, conferring an adaptive advantage. A better understanding of plant circadian rhythms has applications in agriculture, such as helping farmers stagger crop harvests to extend crop availability and securing against massive losses due to weather.
What is the plant expression of circadian rhythm?

The answer:
when to flower
