In contemporary world events and geography, in which city was singer Ariana Grande performing when her concert was hit by a terrorist attack in May 2017?

Introduction / Context:
Recent global events often appear in general knowledge and current affairs questions, especially when they are connected to well known cities and public venues. In May 2017, a major terrorist attack took place at a concert by pop singer Ariana Grande, becoming a widely reported incident that linked popular culture, security issues, and urban geography. This question asks you to recall the specific city in which that tragic event occurred.

Given Data / Assumptions:

• The incident occurred during an Ariana Grande concert in May 2017.
• It is described as a terrorist attack.
• We are choosing among cities in the United Kingdom: Manchester, Birmingham, Liverpool, and London.
• The context is both current affairs and basic knowledge of important European cities.

Concept / Approach:
The attack took place at the Manchester Arena in the city of Manchester, in north west England. It happened at the end of an Ariana Grande concert and led to significant casualties and injuries. While other British cities have also faced security incidents, this particular one is clearly linked in news coverage to Manchester. Therefore, remembering the phrase Manchester Arena attack helps to connect the event with the correct city in this multiple choice question.

Step-by-Step Solution:
Step 1: Recall that the widely reported 2017 attack involving Ariana Grande took place at an indoor arena rather than on an open street or public transport system. Step 2: Connect the venue name with the city: the incident is commonly called the Manchester Arena bombing. Step 3: Recognise that Birmingham and Liverpool are important English cities but are not associated with this particular Ariana Grande concert attack. Step 4: London has suffered other terrorist incidents, especially on public transport and bridges, but those were not linked to this concert event. Step 5: Since news reports and later discussions consistently use the phrase Manchester Arena attack, the correct city must be Manchester. Step 6: Select Manchester as the answer from the given options.

Verification / Alternative check:
Summaries of major terrorist incidents in Europe list the May 2017 Ariana Grande concert bombing under the heading of the Manchester Arena attack. The incident is associated with the city of Manchester, located in the north of England. No credible source connects this Ariana Grande concert tragedy to Birmingham, Liverpool, or London, confirming that Manchester is the correct city for this question.

Why Other Options Are Wrong:

• Birmingham: A major city in the West Midlands region but not the site of the Ariana Grande concert attack in May 2017.
• Liverpool: Another large city in north west England, well known for cultural heritage and football, but not connected with this specific terrorist incident.
• London: Has experienced other attacks on its transport system and public spaces, yet the Ariana Grande concert bombing is not one of them.

Common Pitfalls:
Because several British cities have appeared in news reports about security incidents, learners sometimes mix up which event happened where. Another source of confusion is that London often receives more international media coverage than other cities, leading some people to guess London by default. To avoid these mistakes, remember the phrase Manchester Arena bombing for the Ariana Grande concert attack in 2017, keeping it clearly associated with Manchester.

Final Answer:
The Ariana Grande concert hit by a terrorist attack in May 2017 was in Manchester.
