In international rugby union, which country hosted the 2015 Mens Rugby World Cup tournament?

Introduction / Context:
This general knowledge sports question checks whether you remember the host nation of the 2015 Mens Rugby World Cup. Many learners confuse the country that hosted the tournament with the country that actually won the title, so it is a good test of how well you can separate host facts from winner facts in international rugby union history.

Given Data / Assumptions:
We are given the following key information.

• The event is the Mens Rugby World Cup.
• The specific edition mentioned is the year 2015.
• We are asked to identify the country that hosted the tournament.
• Answer choices include England, New Zealand, South Africa and Australia.

Concept / Approach:
The Rugby World Cup is held every four years and different rugby playing nations host it in turn. The host country may or may not go on to win the tournament, so we must focus on where the matches were staged, not who became champion. The 2015 Mens Rugby World Cup was primarily hosted by England, with most of the matches, including the final, played at stadiums within England. Some fixtures were also played in Cardiff in Wales, but the official host union and main host country for that edition was England. Therefore we recall the historical fact and select the only option that matches the official host nation.

Step-by-Step Solution:
Step 1: Read the year carefully and note that the tournament is the 2015 Rugby World Cup. Step 2: Recall that 2011 was hosted by New Zealand and 2019 was hosted by Japan, so those years do not match 2015. Step 3: Remember that the 2015 edition was centered in England, with the final at Twickenham Stadium in London. Step 4: Compare this fact with the choices and see that England is the correct host country. Step 5: Select England as the final answer.

Verification / Alternative check:
A quick mental timeline of recent Rugby World Cups supports this result. In 2011 New Zealand hosted and also won. In 2015 England hosted but New Zealand won the cup again. Later, in 2019, Japan hosted the tournament. This sequence confirms that the host country for the 2015 edition is England and not the other major rugby nations listed in the options.

Why Other Options Are Wrong:
Option B New Zealand is wrong because New Zealand hosted the 2011 Rugby World Cup, not the 2015 edition. Option C South Africa is wrong because South Africa hosted the 1995 Rugby World Cup, not the 2015 tournament. Option D Australia is wrong because Australia co hosted in 1987 and hosted in 2003, but did not host in 2015.

Common Pitfalls:
A common mistake is to confuse the country that wins the Rugby World Cup with the country that hosts it. In 2015, New Zealand were the champions, so some candidates wrongly pick New Zealand as the host. Another pitfall is mixing up the years of different tournaments. Keeping a rough mental chronology of recent Rugby World Cups helps avoid this confusion in exam questions.

Final Answer:
The correct host country of the 2015 Mens Rugby World Cup was England.
