Input: Article: Vinyl records can be warped by heat, improper storage, exposure to sunlight, or manufacturing defects such as excessively tight plastic shrinkwrap on the album cover. A small degree of warp was common, and allowing for it was part of the art of turntable and tonearm design. "wow" (once-per-revolution pitch variation) could result from warp, or from a spindle hole that was not precisely centered. Standard practice for LPs was to place the LP in a paper or plastic inner cover. This, if placed within the outer cardboard cover so that the opening was entirely within the outer cover, was said to reduce ingress of dust onto the record surface. Singles, with rare exceptions, had simple paper covers with no inner cover.

Now answer this question: What happens if a vinyl comes with a bit of warp?

Output: A small degree of warp was common,

Article: The economy of Himachal Pradesh is currently the third-fastest growing economy in India.[citation needed] Himachal Pradesh has been ranked fourth in the list of the highest per capita incomes of Indian states. This has made it one of the wealthiest places in the entire South Asia. Abundance of perennial rivers enables Himachal to sell hydroelectricity to other states such as Delhi, Punjab, and Rajasthan. The economy of the state is highly dependent on three sources: hydroelectric power, tourism, and agriculture.[citation needed]

Question: What is Himachal Pradesh ranked in the highest per capita of Indian States?
Ans: fourth

Here is a question about this article: In the context of trademarks, this expansion has been driven by international efforts to harmonise the definition of "trademark", as exemplified by the Agreement on Trade-Related Aspects of Intellectual Property Rights ratified in 1994, which formalized regulations for IP rights that had been handled by common law, or not at all, in member states. Pursuant to TRIPs, any sign which is "capable of distinguishing" the products or services of one business from the products or services of another business is capable of constituting a trademark.
What is the answer to this question: What is any sign which is capable of distinguishing one business's product from another business's?
****
So... a trademark

The problem: Answer a question about this article:
Montana's personal income tax contains 7 brackets, with rates ranging from 1 percent to 6.9 percent. Montana has no sales tax. In Montana, household goods are exempt from property taxes. However, property taxes are assessed on livestock, farm machinery, heavy equipment, automobiles, trucks, and business equipment. The amount of property tax owed is not determined solely by the property's value. The property's value is multiplied by a tax rate, set by the Montana Legislature, to determine its taxable value. The taxable value is then multiplied by the mill levy established by various taxing jurisdictionscity and county government, school districts and others.
What is the highest tax bracket in Montana?
****
The answer: 6.9 percent

Problem: Please answer a question about the following article about Middle Ages:
The first years of the 14th century were marked by famines, culminating in the Great Famine of 131517. The causes of the Great Famine included the slow transition from the Medieval Warm Period to the Little Ice Age, which left the population vulnerable when bad weather caused crop failures. The years 131314 and 131721 were excessively rainy throughout Europe, resulting in widespread crop failures. The climate changewhich resulted in a declining average annual temperature for Europe during the 14th centurywas accompanied by an economic downturn.
Along with 131721, what span saw extreme rains in Europe?
A: 131314

Neurophysiologists study the chemical, pharmacological, and electrical properties of the brain: their primary tools are drugs and recording devices. Thousands of experimentally developed drugs affect the nervous system, some in highly specific ways. Recordings of brain activity can be made using electrodes, either glued to the scalp as in EEG studies, or implanted inside the brains of animals for extracellular recordings, which can detect action potentials generated by individual neurons. Because the brain does not contain pain receptors, it is possible using these techniques to record brain activity from animals that are awake and behaving without causing distress. The same techniques have occasionally been used to study brain activity in human patients suffering from intractable epilepsy, in cases where there was a medical necessity to implant electrodes to localize the brain area responsible for epileptic seizures. Functional imaging techniques such as functional magnetic resonance imaging are also used to study brain activity; these techniques have mainly been used with human subjects, because they require a conscious subject to remain motionless for long periods of time, but they have the great advantage of being noninvasive.

Electrodes are often glued to what like in EEG studies?
Answer:
the scalp
