Extract the answer to the question from the following context. Question: what is the fourth word in the first paragraph? Context: Stepper motors are a type of motor frequently used when precise rotations are required. In a stepper motor an internal rotor containing PMs or a magnetically soft rotor with salient poles is controlled by a set of external magnets that are switched electronically. A stepper motor may also be thought of as a cross between a DC electric motor and a rotary solenoid. As each coil is energized in turn, the rotor aligns itself with the magnetic field produced by the energized field winding. Unlike a synchronous motor, in its application, the stepper motor may not rotate continuously; instead, it "steps"starts and then quickly stops againfrom one position to the next as field windings are energized and de-energized in sequence. Depending on the sequence, the rotor may turn forwards or backwards, and it may change direction, stop, speed up or slow down arbitrarily at any time.

Extract the answer to the question from the following context. Question: How is this different from what it written? Context: The papal bull defining the dogma, Ineffabilis Deus, mentioned in particular the patrististic interpretation of Genesis 3:15 as referring to a woman, Mary, who would be eternally at enmity with the evil serpent and completely triumphing over him. It said the Fathers saw foreshadowings of Mary's "wondrous abundance of divine gifts and original innocence" "in that ark of Noah, which was built by divine command and escaped entirely safe and sound from the common shipwreck of the whole world; in the ladder which Jacob saw reaching from the earth to heaven, by whose rungs the angels of God ascended and descended, and on whose top the Lord himself leaned; in that bush which Moses saw in the holy place burning on all sides, which was not consumed or injured in any way but grew green and blossomed beautifully; in that impregnable tower before the enemy, from which hung a thousand bucklers and all the armor of the strong; in that garden enclosed on all sides, which cannot be violated or corrupted by any deceitful plots; in that resplendent city of God, which has its foundations on the holy mountains; in that most august temple of God, which, radiant with divine splendours, is full of the glory of God; and in very many other biblical types of this kind."

Extract the answer to the question from the following context. Question: What year had John Paul not yet reversed his position on laicization of priests, 1980 or 1967? Context: Sacerdotalis caelibatus (Latin for "Of the celibate priesthood"), promulgated on 24 June 1967, defends the Catholic Church's tradition of priestly celibacy in the West. This encyclical was written in the wake of Vatican II, when the Catholic Church was questioning and revising many long-held practices. Priestly celibacy is considered a discipline rather than dogma, and some had expected that it might be relaxed. In response to these questions, the Pope reaffirms the discipline as a long-held practice with special importance in the Catholic Church. The encyclical Sacerdotalis caelibatus from 24 June 1967, confirms the traditional Church teaching, that celibacy is an ideal state and continues to be mandatory for Roman Catholic priests. Celibacy symbolizes the reality of the kingdom of God amid modern society. The priestly celibacy is closely linked to the sacramental priesthood. However, during his pontificate Paul VI was considered generous in permitting bishops to grant laicization of priests who wanted to leave the sacerdotal state, a position which was drastically reversed by John Paul II in 1980 and cemented in the 1983 Canon Law that only the pope can in exceptional circumstances grant laicization.
