In electric power distribution, capacitors are used for power factor correction. Such capacitors often come as three capacitors connected as a three phase load. Usually, the values of these capacitors are given not in farads but rather as a reactive power in volt-amperes reactive (var). The purpose is to counteract inductive loading from devices like electric motors and transmission lines to make the load appear to be mostly resistive. Individual motor or lamp loads may have capacitors for power factor correction, or larger sets of capacitors (usually with automatic switching devices) may be installed at a load center within a building or in a large utility substation.
In what what unit is the capacitance reported for capacitors used in power factor correction?
A: reactive power in volt-amperes reactive (var)

The U.S. Census Bureau reported that in 2000, 24.0% of San Diego residents were under 18, and 10.5% were 65 and over. As of 2011[update] the median age was 35.6; more than a quarter of residents were under age 20 and 11% were over age 65. Millennials (ages 18 through 34) constitute 27.1% of San Diego's population, the second-highest percentage in a major U.S. city. The San Diego County regional planning agency, SANDAG, provides tables and graphs breaking down the city population into 5-year age groups.
What percentage of the population in 2011 were millenials?
A: 27.1%

Possibly in part due to expedited federal habeas corpus procedures embodied in the Antiterrorism and Effective Death Penalty Act of 1996, the pace of executions picked up, reaching a peak of 98 in 1999 and then they declined gradually to 28 in 2015. Since the death penalty was reauthorized in 1976, 1,411 people have been executed, almost exclusively by the states, with most occurring after 1990. Texas has accounted for over one-third of modern executions (although only two death sentences were imposed in Texas during 2015, with the courts preferring to issue sentences of life without parole instead) and over four times as many as Oklahoma, the state with the second-highest number. California has the greatest number of prisoners on death row, has issued the highest number of death sentences but has held relatively few executions.
How many executions occurred in 1959?
A: unanswerable

Historically, Mac OS X enjoyed a near-absence of the types of malware and spyware that affect Microsoft Windows users. Mac OS X has a smaller usage share compared to Microsoft Windows (roughly 5% and 92%, respectively), but it also has traditionally more secure UNIX roots. Worms, as well as potential vulnerabilities, were noted in February 2006, which led some industry analysts and anti-virus companies to issue warnings that Apple's Mac OS X is not immune to malware. Increasing market share coincided with additional reports of a variety of attacks. Apple releases security updates for its software. In early 2011, Mac OS X experienced a large increase in malware attacks, and malware such as Mac Defender, MacProtector, and MacGuard were seen as an increasing problem for Mac users. At first, the malware installer required the user to enter the administrative password, but later versions were able to install without user input. Initially, Apple support staff were instructed not to assist in the removal of the malware or admit the existence of the malware issue, but as the malware spread, a support document was issued. Apple announced an OS X update to fix the problem. An estimated 100,000 users were affected.
Historically, what is near-absent in Mac OS XX compared to Microsoft Windows?
A:
unanswerable
