Answer:
1. Passover = A. A Jewish feast celebrating God's rescue of Israel out of slavery in Egypt
In the book of Exodus chapter 12 you find the story of the first passover, the people of Israel, who were slaves in Egypt, had to stain with the blood of a lamb (with specific characteristics) the door of their houses. This was a sign for one of the plagues God was going to send: he would kill every first born, unless their houses were painted with this blood, if it was so, God would <em>pass over</em> that house and no one would die. In this way, all the people of Israel remained untouched, while the Egyptians had to suffer the loss of their sons and animals.
<em>"The blood will be a sign for you on the houses where you are, and when I see the blood, I will pass over you. No destructive plague will touch you when I strike Egypt." Exodus 12:13</em>
2. Repentance = C. Sorrow for sin that leads to changing one's ways and direction.
Psalm 51 written by David when he understands that he has sinned against God is an execellent example of Repentance.
<em>"For I know my transgressions,</em>
<em> and my sin is always before me.</em>
<em>Against you, you only, have I sinned</em>
<em> and done what is evil in your sight(...)" </em>Psalm 51: 3-4
3. Trinity = D. The union of the three divine persons in one God head.
Father, Son and the Holy Spirit are one God. A very useful way of understanding this is by thinking of GOD as if he was WATER, water has three different states: SOLID, LIQUID or GAS, whatever the state is, water continues to be water, even if it is solid, liquid or gas. In the same way, God is always God.
4. Prophecy=B. To declare or predict through divine guidance.
Isaiah is a book that contains lots of prophecies in the Bible, as well as the book of Revelations.
