The 91st Academy Awards ceremony to honour the best films of 2018 was held at the Dolby Theatre in which city?

Introduction / Context:
The Academy Awards, also known as the Oscars, are among the most famous film awards in the world. They are organised annually by the Academy of Motion Picture Arts and Sciences and usually take place at a fixed venue in the United States. The 91st Academy Awards honoured the best films of 2018, and this question tests whether you remember the city in which the Dolby Theatre, the regular Oscars venue, is located.

Given Data / Assumptions:

• The event is the 91st Academy Awards ceremony.
• The venue mentioned is the Dolby Theatre.
• The options list four major world cities: Tokyo, Los Angeles, Paris, and Sydney.
• The task is to identify the correct city for the Oscars venue.

Concept / Approach:
The Dolby Theatre is located in Hollywood, which is a neighbourhood of Los Angeles in the state of California, United States. The Oscars ceremonies have been held there regularly for many years. Therefore, whenever a question mentions Dolby Theatre in relation to the Academy Awards, the correct city is Los Angeles. The other cities in the options are important global centres but do not host the Oscars.

Step-by-Step Solution:
Step 1: Recognise the Academy Awards as an American film award ceremony. Step 2: Recall that the Oscars are strongly associated with Hollywood, which is in Los Angeles. Step 3: Remember that the Dolby Theatre is a well known venue on Hollywood Boulevard and is the regular site for the Oscars. Step 4: Among the options, identify Los Angeles as the only city that matches this description. Step 5: Select Los Angeles as the correct answer.

Verification / Alternative check:
A simple verification method is to picture news images of the red carpet events. The media almost always uses phrases like Hollywood and Los Angeles when describing the Oscars arrival of actors and directors. Tokyo, Paris, and Sydney are never mentioned as Oscars host cities in standard reporting. Thus, if you connect Dolby Theatre with Hollywood and Hollywood with Los Angeles, you can be confident in your answer.

Why Other Options Are Wrong:
Tokyo is the capital of Japan and hosts many film festivals but not the Academy Awards ceremony.
Paris is a major European cultural centre but is not the home of the Oscars.
Sydney is a key Australian city and may host local award shows, yet it has no connection with the Dolby Theatre or the Academy Awards.

Common Pitfalls:
Some learners may confuse the Oscars with international film festivals like Cannes or Berlin, which are held in European cities. Others may not immediately connect Dolby Theatre with Hollywood. To avoid such mistakes, fix in your mind a simple association: Oscars, Dolby Theatre, Hollywood, Los Angeles. This chain will help you answer any similar question quickly.

Final Answer:
The 91st Academy Awards ceremony at the Dolby Theatre took place in Los Angeles.
