Honkai Star Rail Ministry of Education Quiz Answers
Part 1 Question 1
Which are there more of: prime numbers, or natural numbers?
- Prime numbers.
- Natural numbers.
- The same.
- What are prime numbers?
Click to show answer to Part 1 Question 1
To answer this, you need to apply the principles of set theory, which is usually taught in university level mathematics classes. In short, both prime numbers and natural numbers are infinite (but some infinities can be bigger than others), and infinite in a way that every prime number can be matched to exactly one natural number (1st prime number is matched to 1, 2nd prime number is matched to 2, etc.).
Part 1 Question 2
The Limesteins have a large parking lot filled with 42 cars. One day, a thief stole wheels from several cars. Now, several cars only have 3 wheels left. While appraising damages, the insurer bent down and counted a total of 154 wheels across the lot. How many cars had their wheels stolen?
Click to show answer to Part 1 Question 2
The original number of wheels should be 42 x 4 = 168. 168 – 154 = 14 wheels missing, and since the question states some cars have 3 wheels (i.e., are missing just 1 wheel), that also means 14 cars had their wheels stolen
58 is First Snow, and First Snow is 0.
39 is Summershade Bamboo, and Summershade Bamboo is 14.
99 is Ball Peony, and Ball Peony is 8.
27 is Sunshine, and Sunshine is 4.
How much does First Snow, Summershade Bamboo, Ball Peony, and Sunflower added together make?

This is a pretty cryptic puzzle that requires some creative thinking.
Each object represents a number, and “is” represents some function applied to a number to get another number. It turns out that the function is multiplying the digits of the input together:
- 58 –> 5 x 8 = 40 –> 4 x 0 = 0
- 39 –> 3 x 9 = 27 –> 2 x 7 = 14
- 99 –> 9 x 9 = 81 –> 8 x 1 = 8
- 27 –> 2 x 7 = 14 –> 1 x 4 = 4
So adding them together gives you 40 + 27 + 81 + 14 = 162.
The Limesteins’ wheel thief was apprehended, with the guards taking in three suspects: Jack, Chris, and Eric. The three argued, with Jack blurting: “Chris is the one who stole the wheels!”
The quick-witted Gepard quickly found the culprit. To test his aide, Gepard said cryptically without revealing the thief: “How strange. Of the three, only the thief did not lie.”
Who was the thief that stole the Limesteins’ wheels?

If Jack was the thief, his statement would be true, which would make Chris the thief – this is a contradiction, which means Jack is not the thief.
Since Jack is not the thief, he lied, so Chris is also not the thief. This just leaves Eric.

Howard, Philip, and Joyce: among them is a good man, a bad man, and a liar. The good man only tells the truth; the bad man only lies; and the liar… Well, he would say anything – sometimes the truth, and sometimes lies. One day, Joyce said: “Philip is either the good man or the bad man.” Then, Philip said: “Either Howard or Joyce is the good man.” Which of these three is the liar?
Click to show answer to Part 4
Philip cannot be the good man, because then his statement that Howard or Joyce is the good man would be true, which is clearly a contradiction.
Philip cannot be the bad man, because then his statement that Howard of Joyce is the good man would be a lie, which would make Philip the good man, which is clearly a contradiction. Therefore Philip is the liar.

Count the number of circles among the numerals on the left side. 8’s have two circles each, so 8848 must be 6.
Hook is playing a game called “Guess the Flower Color” with her friends.
She invited Julian, Luka, and Big Sister who always plays with them – and stuck a flower in each one’s hair. There are four flowers – two white, two purple – and nobody including Hook looked at their own flower nor anybody else’s flower.
Next, she asked everyone to step forward and form a line. Hook, Julian, Luka, and then Big Sister stood in order. Only looking at the person straight ahead is allowed, and nobody may turn around or peek at anyone else’s flower.
To keep things fair, Hook blindfolded Big Sister – because she’s so tall!
However, while they can’t see their own flowers, we can as we walk by: Hook and Luka have white flowers, while Julian and Big Sister have purple ones.
Despite Hook’s best and fairest intentions, only one person in this game will be able to guess what color the flower they have on their head is. Who is that person?
- Big Sister
Click to show answer to Part 6
Big Sister is blindfolded, and there’s no one in front of Hook, so neither of them can determine the color of their own flowers.
Luka sees one white and one purple flower, so cannot determine the color of his flower.
Julian knows that if Luka had seen two white flowers or two purple flowers, Luka would be able to guess immediately his own flower. Since Luka does not make a guess, Julian can deduce that Luka sees one white and one purple flower. Since Julian sees Hook’s flower is white, Julian knows his must be purple.
I heard that there’s an ancient treasure buried in an inconspicuous corner of the snow plains.
Sampothe explorer – Tall, Blue, and Handsome – found the treasure after quite an adventure, and before them, they found two talking gates: One gold, one silver.
One of these two doors only tells the truth, while the other only tells lies. Behind one of these doors lies a treasure, behind the other lies an ancient monster. A note on the treasure map advises: The two doors will only answer one question.
Sampo– Tall, Blue, and Handsome – gives it some thought before asking the silver door, “What would the gold door say about the thing that lies behind you?” The silver door answers, “It would say, there is treasure behind me.” Which door should Sampo– Tall, Blue, and Handsome – open?
- Open the gold door
- Open the silver door
- Open the one with monsters
Click to show answer to Part 7
Open the gold door.
If the silver door tells the truth, then the gold door would lie about the treasure being behind the silver door, and the silver door would correctly state this – which would mean the treasure is behind the gold door.
If the silver door tells lies, then the gold door would tell the truth about the treasure being behind the gold door, and the silver door would lie about what the gold door said – which would also mean the treasure is behind the gold door.
So regardless of which door tells the truth, you should open the gold door.
The Belobog Academy has discovered a new, invasive species of algae that can double itself in just one day, and in just 30 days fill a whole reservoir – contaminating the water supply. How many days would it take for the algae to fill half the reservoir?
- Day fifteen
- Day twenty-nine
- Day thirty-one
Click to show answer to Part 8
Since the algae doubles every day, it takes just one day to go from half the reservoir to the whole reservoir, so the day before 30 days would fill up half.
