Problem Description:
The image is a line graph titled
"Participation by Club Members". It shows the percentage of club members participating in three activities over time:
swimming,
team sports, and
gym activities. The x-axis represents the years from 1995 to 2015, and the y-axis represents the percentage of club members (ranging from 0% to 60%).
The task is to analyze the trends in participation for each activity over the given period and summarize the key observations.

Solution:
#### Step 1: Analyze the Trend for Each Activity
1.
Swimming (Blue Line):
- In 1995, swimming had the highest participation at around
50%.
- Over the years, participation in swimming steadily declined.
- By 2015, participation in swimming dropped to approximately
15%.
- Key Observation: Swimming experienced a consistent decline in popularity among club members.
2.
Team Sports (Orange Line):
- In 1995, team sports had a moderate participation rate of about
30%.
- Participation in team sports remained relatively stable until around 2005.
- From 2005 to 2010, there was a noticeable increase, reaching a peak of approximately
40%.
- After 2010, participation began to decline slightly, stabilizing around
30% by 2015.
- Key Observation: Team sports showed initial stability, followed by a rise and then a slight decline, but overall maintained a moderate level of participation.
3.
Gym Activities (Gray Line):
- In 1995, gym activities had the lowest participation, starting at around
5%.
- Participation in gym activities gradually increased over time.
- By 2010, it reached approximately
25%.
- After 2010, participation stabilized around
25%.
- Key Observation: Gym activities saw a steady increase in popularity and eventually surpassed swimming and team sports in terms of participation by 2015.
#### Step 2: Compare the Trends
-
Swimming: Declined significantly over the entire period.
-
Team Sports: Initially stable, then increased, and finally stabilized at a moderate level.
-
Gym Activities: Consistently increased and became the most popular activity by 2015.
#### Step 3: Summary of Observations
-
Swimming lost popularity over the years, with participation dropping from
50% in 1995 to
15% in 2015.
-
Team Sports showed fluctuation but remained moderately popular, peaking at
40% in 2010 and stabilizing around
30% by 2015.
-
Gym Activities gained significant popularity, increasing from
5% in 1995 to
25% by 2015, becoming the most preferred activity by the end of the period.

\boxed{
\text{Swimming declined significantly, team sports fluctuated but remained moderate, and gym activities increased steadily to become the most popular by 2015.}
}
\]
