The first-ever World Tuna Day observed by the United Nations fell on which date?

Introduction / Context:
World Tuna Day was established by the United Nations to highlight the importance of tuna for food security, livelihoods and marine ecosystems. The first ever World Tuna Day observed by the UN took place on May 2, 2017. This question specifically tests whether you remember the exact inaugural date, which is important for those preparing for exams that focus on UN initiatives, fisheries, and environmental awareness.

Given Data / Assumptions:
- The observance is World Tuna Day, recognized by the United Nations.
- The question is about the date of the first ever UN observed World Tuna Day.
- The options include several dates in early May 2017 and one additional marine related date, World Oceans Day, as a distractor.

Concept / Approach:
The conceptual point is to differentiate between one time inaugural dates and annually observed days. For World Tuna Day, the UN marked May 2, 2017 as the first celebration under its banner. To remember this, you can connect tuna to the number “2” in May: tuna sounds like “two na” in playful memory tricks, which suggests the second day of May. Although this is a simple mnemonic, it can help you recall the precise date quickly in an exam.

Step-by-Step Solution:
Step 1: Recognize that this is about the first ever UN observed World Tuna Day. Step 2: Recall that the UN officially observed World Tuna Day for the first time on May 2, 2017. Step 3: Examine the options and note that “May 2, 2017” appears as one of the choices. Step 4: Connect the idea of tuna with the number two as a quick memory aid, reinforcing the second day of May. Step 5: Choose “May 2, 2017” as the correct answer since it aligns perfectly with the UN announcement and the inaugural event.

Verification / Alternative check:
To verify, recall that World Oceans Day is observed on June 8 each year, which is another marine related date. Because June 8 is already occupied by World Oceans Day, the tuna specific observance is placed earlier in the year. Knowing this helps you eliminate the June 8 option and focus on the early May dates, where May 2, 2017 stands out as the correct one mentioned in news reports and UN press releases about the first World Tuna Day.

Why Other Options Are Wrong:
May 1, 2017: This date is associated with International Workers Day or Labour Day in many countries, not the first World Tuna Day.
April 2, 2017: Not linked to World Tuna Day and would cause confusion with other April observances.
May 3, 2017: Already used for World Press Freedom Day and not the inaugural tuna observance.
June 8, 2017: Recognized as World Oceans Day, a broader marine environment observance, but not the specific tuna focused day in this question.

Common Pitfalls:
One common pitfall is to mistakenly choose June 8 because it is strongly associated with oceans and marine life, and candidates may assume tuna would be celebrated on the same day. Another error is to pick May 1 through simple pattern recognition, ignoring that Labour Day falls on that date. Paying attention to the exact wording “first ever World Tuna Day” and tying tuna to the second day of May helps avoid these errors.

Final Answer:
Correct option: May 2, 2017
