According to the canonical gospels, Jesus, whom Christians believe to be the Son of God as well as the Messiah (Christ), was arrested, tried, and sentenced by Pontius Pilate to be scourged, and finally crucified by the Romans. Jesus was stripped of his clothing and offered wine mixed with gall to drink, before being crucified. He was then hung for six hours (according to Mark's Gospel) between two convicted thieves. During this time, the soldiers affixed a sign to the top of the cross stating "Jesus of Nazareth, King of the Jews" in three languages. They then divided his garments among them, but cast lots for his seamless robe. After Jesus' death they pierced his side with a spear to be certain that he had died. The Bible records seven statements that Jesus made while he was on the cross, as well as several supernatural events that occurred.
Who was the person that tried Jesus?
****
The answer: Pontius Pilate


The problem: Answer a question about this article:
All the electromagnetic motors, and that includes the types mentioned here derive the torque from the vector product of the interacting fields. For calculating the torque it is necessary to know the fields in the air gap . Once these have been established by mathematical analysis using FEA or other tools the torque may be calculated as the integral of all the vectors of force multiplied by the radius of each vector. The current flowing in the winding is producing the fields and for a motor using a magnetic material the field is not linearly proportional to the current. This makes the calculation difficult but a computer can do the many calculations needed.
How is torque determined?
****
The answer: from the vector product of the interacting fields

Hops contain several characteristics that brewers desire in beer. Hops contribute a bitterness that balances the sweetness of the malt; the bitterness of beers is measured on the International Bitterness Units scale. Hops contribute floral, citrus, and herbal aromas and flavours to beer. Hops have an antibiotic effect that favours the activity of brewer's yeast over less desirable microorganisms and aids in "head retention", the length of time that a foamy head created by carbonation will last. The acidity of hops is a preservative.
What is the main goals for the sweetness of beer?
****
The answer:
malt
