Answer 1

To determine where App Upper P should be placed in a Venn diagram representing its downloads across the years 2018, 2019, and 2020, we first need to examine the information you've provided about the most downloaded apps during those years.

- In **2018**, App Upper P was ranked 3rd.
- In **2019**, App Upper P is not mentioned.
- In **2020**, App Upper P is not mentioned.

Knowing this, we can summarize App Upper P's appearances:

- **2018**: Present
- **2019**: Absent
- **2020**: Absent

In a typical Venn diagram for three sets (years in this case), each region represents a different combination of presence across the three years. The regions are labeled as follows:

- **Region I**: Present in 2018 only
- **Region II**: Present in both 2018 and 2019
- **Region III**: Present in both 2018 and 2020
- **Region IV**: Present in 2019 only
- **Region V**: Present in both 2019 and 2020
- **Region VI**: Present in both 2018, 2019, and 2020
- **Region VII**: Present in 2020 only
- **Region VIII**: Present in both 2018 and 2020

Since App Upper P is only present in 2018 and absent in both 2019 and 2020, it falls into Region I.

Therefore, App Upper P should be placed in **Region I** of the Venn diagram.
