Explanation
Since we need to focus on 1 country -> Japan, let's filter on it first as follows:
1) Drag Country to the filter shelf, and choose only Japan. Click OK.
2) Read the Question Carefully, we need to break down the visualisation by Region, then by Country, and then by State. So let's do that:
Drag Region to the column shelf, followed by Country. Drill down into Country to include states as well.
Then drag Quantity to the Row Shelf, and change the Aggregation to AVERAGE.
The following is our visualisation:
Now that you think of it, EVEN IF YOU REMOVE THE REGION, THE ANSWER REMAINS THE SAME.
Such elements will be present in the actual exam too, just to make the question sound a little difficult, but actually it is pretty straightforward :)

Explanation
You can show trend lines in a visualization to highlight trends in your data.
To add trend lines to a view, both axes must contain a field that can be interpreted as a number. For example, you cannot add a trend line to a view that has the Product Category dimension, which contains strings, on the Columns shelf and the Profit measure on the Rows shelf.
However, you can add a trend line to a view of sales over time because both sales and time can be interpreted as numeric values.

質問 # 85
正誤問題：ディメンションの地理的役割を変更することが可能
- A. 偽

正解：B
解説：
Explanation
A geographic role associates each value in a field with a latitude and longitude value.
Assigning a geographic role based on the type of location (such as state versus postcode) helps ensure that your data is plotted correctly on your map view. For example, you can assign the City geographic role to a field that contains a list of city names.
To assign a geographic role to a field:
In the Data pane, click the data type icon next to the field, select Geographic Role, and then select the geographic role you want to assign to the field.
When you assign a geographic role to a field, Tableau adds two fields to the Measures area of the Data pane:
Latitude (generated) and Longitude (generated).
These fields contain latitude and longitude values and are assigned the Latitude and Longitude geographic roles.
If you double-click each of these fields, Tableau adds them to the Columns and Rows shelves and creates a map view using the Tableau background map.

Since Sales is a measure, it can easily be depicted via size.
To drill down and change the level of detail, Country is the correct choice since it will contain STATE. We can then depict the various states by different shapes such as circle, square etc.
Finally, the Profit can be depicted via a color! Eg - Red for poor and green for excellent profits!

A Pareto chart is a type of chart that contains both bars and a line graph, where individual values are represented in descending order by bars, and the ascending cumulative total is represented by the line.
On the primary axis, bars are used to show the raw quantities for each dimension member, sorted in descending order.
On the secondary axis, a line graph is used to show the cumulative total in percent format.
質問 # 93
はいまたはいいえ：ビューの寸法の数を増やすと、マークの数が増えます
- A. はい
- B. いいえ
正解：A
解説：
Explanation
Of course! As an example, see below:
1) Using the Sample Superstore data, let's plot a bar chart showing the Sales for each Category:
Observe that we have 3 marks - Each bar in a bar chart is called a mark. Similarly, each point in a scatter plot is also a mark , and so on for all charts.
1 row by 3 columns means that clearly on the y-axis (Sales), we have only a single mark - a single continous axis, but 3 different marks (Technology, Furniture and Office supplies ) on the x-axis.
2) Now let's add subcategory to the view as well (another dimension):
Observe that the number of marks has increased - i.e the number of Bars.
Also, notice we now have 1 row and 17 columns. Simply because 1 row = Sales (on the y-axis), and on the x-axis, we have 17 different columns (i.e product sub categories!!)
