We have a membership level system that requires you to pass quiz for every promotion. The quizzes are hosted on our open Learning Management System (LMS), called SIAI Class, an open school version of SIAI’s Gordon School of Business. The basic membership only requires your login via Google or Microsoft Authorization. This will give Level 0 on The Economy Senate and empty registration to SIAI Class. Most activities on The Economy Senate require at least Level 1, so you must pass the promotion quiz. Below is the promotion quiz link
The quiz has 3 questions for maximum 10 minutes and only 3 attempts are allowed. If you fail all three, you are not allowed to be promoted, and unfortunately we are unwilling to give you another chance.
The questions are intended to be complicated. Each question tests your mathematical intuition, deductive reasoning, and reading skills. We have consistent record that almost all applicants fail, unless they have prior knowledge or 3rd party support.
This is our way to ensure that The Economy Senate is a clean, healthy, constructive, and most importantly intellectual community. Nonetheless, we do not like you to fail and turn around. As such, we have decided to provide you a guide document so that anyone patient and diligent enough can leverage the instruction and use it to pass the quiz.
Below is a rather lengthy document to explain the 3 questions in Level 1 quiz. Plz carefully read every detail so that you can pass in your first attempt. If you think you are smart enough, or if you want to test your intelligence, you can skip and go straight to the test. If fail, then come back anytime before you use up all 3 attempts.
Questions are given with random order, as well as choices for each question. Sometimes we change the labels, so you really have to carefully read all, otherwise you won’t be able to get the right answer.
Q. GIAI organisational chart
There are 4 types of business sections under GIAI’s umbrella. The Economy Senate is one of the sub-services in The Economy, for example. Institutionally, GIAI Council is the ultimate decision maker of all services except ones in the GIAI Partners column. GIAI provides ranking algorithms to partner services.
Q. The Economy Network chart
The Economy is mainly a research-hybrid news service. Each function covers specific topics of the service, while the text contents are all fed to GIAI Capital’s LLM to market signal model.

Q. Deductive reasoning: When is the surprise exam day?
One of the days in the week will be the exam day. And, the key element in this exam is ‘surprise’. It has to meet the condition that the exam is ‘surprise’.
With that condition in mind, let’s think of a student on Thursday night. If there has not been any exam, there certainly will be a exam on Friday, unless the professor lied about it. Then, will it be a ‘surprise’ exam? It is not. So, Friday cannot be the exam day.
Then, put yourself on Wednesday night. Since we know that Friday cannot be the ‘surprise’ exam day, if there has not been any exam by Wednesday, then there must be exam on Thursday. Will it then qualify ‘surprise’? Well, it is not surprise anymore, if you know with certainty.
The same logic can be applied on Tuesday night. Now you know that there will be no ‘surprise’ exam on Friday and Thursday, therefore it has to be Wednesday. If you have certainty that it will be Wednesday, then does it qualify to be ‘surprise’?
By exactly the same logic, the ‘surprise’ exam will be on Monday, probably right after the professor announced it.
