The 18th Asian Games also known as Asiad in 2018 were scheduled to be held in which host city?

Introduction / Context:
This question refers to the 18th edition of the Asian Games, often called Asiad, which took place in 2018. Asian Games host cities are a favourite topic in general knowledge and sports awareness sections, especially for exams in Asian countries.

Given Data / Assumptions:
Important data from the question is as follows.

• The event is the 18th Asian Games, Asiad.
• The year mentioned is 2018.
• We must identify the host city from four major Asian cities.
• Options include Bangkok, Jakarta, Beijing and Seoul.

Concept / Approach:
The 18th Asian Games were co hosted by two Indonesian cities, Jakarta and Palembang, with Jakarta as the main host city. The opening and closing ceremonies and many major events were held in Jakarta. Therefore, when the question asks for the host city, the correct answer is Jakarta. Bangkok, Beijing and Seoul have hosted other multi sport events but not the 2018 Asian Games.

Step-by-Step Solution:
Step 1: Note that we are dealing with the 2018 edition of the Asian Games. Step 2: Recall that Indonesia was the host country and that two cities were prominently involved. Step 3: Remember that Jakarta was the main host city, with Palembang as a co host. Step 4: Compare this memory with the options and pick Jakarta, which matches the actual host city. Step 5: Confirm that Bangkok is in Thailand, Beijing in China and Seoul in South Korea and that they did not host Asiad 2018.

Verification / Alternative check:
You can verify by recalling the mascot and logo of the Jakarta Palembang 2018 Asian Games. Official branding and news coverage repeatedly used the phrase Jakarta Palembang 2018, which fixes Jakarta in your mind as the main host city. This cross check removes confusion with Beijing, Seoul or Bangkok, which are associated with other Olympic or Asian events in different years.

Why Other Options Are Wrong:
Option A Bangkok is wrong because Bangkok has hosted earlier Asian Games but not the 2018 edition. Option C Beijing is incorrect because Beijing is more famously linked with the 2008 Summer Olympics, not Asiad 2018. Option D Seoul is wrong since Seoul is known for the 1988 Summer Olympics and earlier Asian events, not the 18th Asian Games in 2018.

Common Pitfalls:
A typical mistake is to mix up host cities of the Olympics with those of the Asian Games, especially Beijing and Seoul. Another pitfall is to remember that the Games were in Indonesia but forget the exact city. Linking the keyword Jakarta Palembang 2018 with Indonesia in your memory will help you answer similar questions quickly.

Final Answer:
The 18th Asian Games in 2018 were hosted mainly in Jakarta.
