:00

The wave height of the Java Sea affects maritime traffic. Traffic in December is busier than in November. October is busier than December. January is not busier than November, but busier than February.

The shipping traffic estimated to be the second busiest occurs in the month of ...

Explanation

Let's analyze the shipping traffic volume for each month based on the given information. We will use inequality signs to compare the busyness between months.

Statement	Mathematical Analysis
December is busier than November	$\text{December} > \text{November}$
October is busier than December	$\text{October} > \text{December}$
January is not busier than November	$\text{January} \le \text{November}$
January is busier than February	$\text{January} > \text{February}$

Based on the points above, we can arrange the order of busyness from the busiest to the quietest:

From the first two points, we get the order:

$\text{October} > \text{December} > \text{November}$
From the last two points, we know that January is below or equal to November, and February is below January:

$\text{November} \ge \text{January} > \text{February}$

If we combine all this information, the complete order is:

\text{October} \xrightarrow{\text{busier}} \text{December} \xrightarrow{\text{busier}} \text{November} \xrightarrow{\text{busier/equal}} \text{January} \xrightarrow{\text{busier}} \text{February}

From this sequence, we can determine the ranking of busyness:

Busiest: October
Second busiest: December
Third: November
Fourth: January
Fifth: February

Conclusion: The shipping traffic estimated to be the second busiest occurs in the month of December.

Therefore, the correct answer is December.
