Hello I am glad you asked this question and thanks for the A2A. This question requires a 101 Summary because they are Catholic in nature and connects the works of the Devil instead of God's power.
(1- Adam and Eve ate of the Tree of Knowledge because they were fooled into it they received eternal judgment:
Genesis 3:19
Living Bible
19 All your life you will sweat to master it, until your dying day. Then you will return to the ground from which you came. For you were made from the ground, and to the ground you will return.”
How did God administer this punishment?
Genesis 3:24
Modern English Version
24 He drove the man out, and at the east of the garden of Eden He placed the cherubim and a flaming sword which turned in every direction, to guard the way to the tree of life.

(2. Why are the Covenants made by Jesus Christ and established before his death for the children of Adam and Eve?
a. Hebrews 9:20
Modern English Version
20 saying, “This is the blood of the covenant that God has commanded you to keep.”
The entire chapter 9 of Hebrews explains the condition of the covenant that we must live under to reverse the penalty of death because access to the Tree of Life was forbidden.
b. Colossians 2:17
Living Bible
17 For these were only temporary rules that ended when Christ came. They were only shadows of the real thing—of Christ himself.
The entire chapter 10 of Hebrews explains the role of Christ in reversing the penalty of death given to humans by offering his on life as a ransom, the covenant agreement that provides salvation for all the world.

(3. How will Christ restore life to the world?
Luke 22:29
Tree of Life Version
29 And just as My Father has granted Me a kingdom, so I grant to you
Romans 6:23
Living Bible
23 For the wages of sin is death, but the free gift of God is eternal life through Jesus Christ our Lord.
Revelation 21:5-8
Easy-to-Read Version
5 The one who was sitting on the throne said, “Look, I am making everything new!” Then he said, “Write this, because these words are true and can be trusted.”
6 The one on the throne said to me, “It is finished! I am the Alpha and the Omega, the Beginning and the End. I will give free water from the spring of the water of life to anyone who is thirsty. 7 All those who win the victory will receive all this. And I will be their God, and they will be my children. 8 But those who are cowards, those who refuse to believe, those who do terrible things, those who kill, those who sin sexually, those who do evil magic, those who worship idols, and those who tell lies—they will all have a place in the lake of burning sulfur. This is the second death.”
Now your questions can be answered successfully which would be NO to all four questions because:
Hebrews 10:1
Tree of Life Version
Perfect Pardon in the New Covenant
10 The Torah has a shadow of the good things to come—not the form itself of the realities. For this reason it can never, by means of the same sacrifices they offer constantly year after year, make perfect those who draw near.
Galatians 3:24
New King James Version
24 Therefore the law was our tutor to bring us to Christ, that we might be justified by faith.
