In which of the following cities were the 2020 Summer Olympic Games scheduled to be held?

Introduction / Context:
The 2020 Summer Olympic Games are a major landmark in recent sports history, especially because of the unprecedented global events that affected their scheduling. Even though the Games were ultimately held in 2021, they retained the name Tokyo 2020. This question focuses on the basic but important fact of which city was selected as the host for the 2020 Summer Olympics, a very common topic in GK exams.

Given Data / Assumptions:

• The event is the 2020 Summer Olympic Games.
• The options are London, Paris, Tokyo and Moscow.
• We assume the official International Olympic Committee (IOC) designation of the host city.

Concept / Approach:
The concept here is simple recall of host cities and years. Tokyo, the capital of Japan, was awarded the 2020 Summer Olympics. London last hosted the Summer Olympics in 2012. Paris has been chosen to host the 2024 Summer Olympics, and Moscow hosted the Games in 1980. Therefore, matching the year 2020 with the correct city, Tokyo, is the core of the solution.

Step-by-Step Solution:
Step 1: Recall the sequence of recent Summer Olympic host cities: Beijing 2008, London 2012, Rio de Janeiro 2016, Tokyo 2020, and Paris 2024.Step 2: From this sequence, identify that Tokyo is the city associated with the 2020 Games.Step 3: Compare this with the options: London (2012), Paris (2024), Tokyo (2020) and Moscow (1980).Step 4: Confirm that none of the other cities in the options were scheduled to host the 2020 Summer Olympics.Step 5: Conclude that Tokyo is the correct answer.

Verification / Alternative check:
You can verify this by recalling branding materials, logos and media coverage referring to the event as Tokyo 2020, even though the Games eventually took place in 2021. Sports news, athlete interviews and official Olympic websites consistently use the Tokyo 2020 label. This consistency confirms that Tokyo is the city associated with the 2020 Summer Olympics, unlike London, Paris or Moscow in that specific context.

Why Other Options Are Wrong:
London hosted the Olympics in 2012, not in 2020. Paris is scheduled for a later edition, namely 2024. Moscow was the host city for the 1980 Summer Olympics, during a different era. While all these cities have Olympic histories, none of them correspond to the 2020 Games, making them incorrect for this question.

Common Pitfalls:
Some learners may confuse the shifting of the event to 2021 with a change in host city or year and may hesitate about the answer. Others may mix up Paris 2024 and Tokyo 2020, as both have been heavily discussed in recent news. To avoid such errors, it is helpful to memorise a simple line such as "Tokyo 2020 – Paris 2024" that clearly associates these years with their respective host cities.

Final Answer:
The 2020 Summer Olympic Games were scheduled to be held in Tokyo.
