In political systems, what is the official name of the national parliament of Sweden?

Introduction / Context:
Parliament names are a favourite topic in general knowledge and international affairs sections. Each country often has a traditional or local language term for its legislature. Sweden has a specific term for its parliament that you must remember for such questions.

Given Data / Assumptions:

• The country is Sweden.
• We are asked about the official name of its parliament.
• Options list Storting, Knesset, Riksdag, and Sejm, which are all real names of different national parliaments.

Concept / Approach:
The approach is to match each parliamentary name with its country. Once you correctly recall which country uses which term, you can pair Sweden with the correct one. This is essentially a fact recall question.

Step-by-Step Solution:
Step 1: Recall that the parliament of Sweden is called the Riksdag. This is a well known term in European politics.Step 2: Storting is the name of the parliament of Norway, not Sweden.Step 3: Knesset is the Israeli parliament.Step 4: Sejm is the lower house of the parliament in Poland.Step 5: Therefore, the only option that correctly names Sweden parliament is Riksdag.

Verification / Alternative check:
Any standard GK book on international organizations and constitutions lists Riksdag as the Swedish parliament. News articles about Swedish elections also routinely mention the Riksdag.

Why Other Options Are Wrong:
Storting: Correct for Norway, not for Sweden.Knesset: This term belongs to Israel parliament.Sejm: This is a part of the Polish parliament structure.

Common Pitfalls:
Because all four options refer to real parliaments, students may mix them up if they only have partial knowledge.A common mistake is to guess based on which name sounds Scandinavian, but careful study reveals that only Riksdag belongs to Sweden.

Final Answer:
The national parliament of Sweden is called the Riksdag.
