Key Insights

Team B demonstrated the highest consistency and achieved the top 500-day average balance, suggesting it earned at least one scoring point and holds the tiebreaker. Team B also appears to have led in balance for the majority (>80%) of days. Team C, after a poor start, dramatically rebounded, and its half-balance overtook other teams' full balances during the late contest, likely earning the crossover point. All three teams' half-balances overtook at least one competitor's full-balance at various points. Team A displayed the highest volatility, sometimes outpacing others, but its average and stability were weaker than team B's.

Step-by-Step Solution

Question 1: Identifying the Winner of the Contest

Complete Statement:

In the contest, Team [BLANK 1] was declared the winner

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: In the contest
    _ Meaning: Refers to the 500-day simulated currency-trading competition among Teams A, B, and C.
    _ Relation to Chart: The chart shows the performance (balances) of all three teams throughout the contest.
    _ Important Implications: We need to consider all teams' results over the 500 days and use the contest scoring rules to decide the winner.

• Statement Breakdown 2:
  • Key Phrase: was declared the winner
    _ Meaning: The team that earned the most points according to the three criteria set by the contest rules wins.
    _ Relation to Chart: To determine the winner, check the three criteria using the visual data: half-balance crossings, 500-day balances (reference lines), and daily leadership.
    _ Important Implications: We must estimate which team gained the most points based on visible features of the chart.

• What is needed: Which team (A, B, or C) was the contest winner according to the points earned from the three criteria.

Solution:

• Condensed Solution Implementation:
  Estimate each team's performance using the chart. First, compare the reference lines for 500-day averages, which hover at about $190 for Team A and about $180 for Teams B and C. Next, check for instances where a team's half-balance line crossed above another team's full-balance line: all teams display such crossings during the contest. Finally, evaluate which team's balance was the highest for the most days: Team A leads for roughly the first and last 150 days, while Team B leads for the middle portion. Overall, Team A leads for the majority of days.
• Necessary Data points:
  Team A's 500-day average is about $190, higher than Teams B and C (about $180 each). Team A's half-balance line clearly crosses above full-balance lines. Team A's full-balance line is on top at the beginning and end of the period.
  _ Calculations Estimations:
  Team A leads for about 300 out of 500 days, but the requirement is at least 400 days (80%) for that scoring point. However, Team A definitively satisfies two criteria: highest average and at least one half-balance crossover.
  _ Comparison to Answer Choices:
  Among the choices, Team A is the only team that consistently achieves the highest average and at least one half-balance crossover, making Team A the clear winner.

FINAL ANSWER Blank 1: A

Question 2: Calculating Points Earned by the Winner

Complete Statement:

after winning [BLANK 2] points

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: after winning [BLANK 2] points
    _ Meaning: We are to find the total points Team A earned in the contest from the three possible criteria.
    _ Relation to Chart: Check, using the chart, how many criteria Team A fulfilled: (1) half-balance crossing, (2) highest 500-day average, (3) led for at least 80% of the days.

• What is needed: How many contest points (out of 3) Team A earned.

Solution:

• Condensed Solution Implementation:
  Go through each criterion: Criterion 1—Team A's half-balance line crosses above other teams' full-balance lines. Criterion 2—Team A clearly has the highest 500-day average. Criterion 3—Team A led more days than Team B or C but likely not 80% of the days (not at least 400 out of 500 days). So, Team A fulfills two out of three criteria.
• Necessary Data points:
  Half-balance crossovers: present for Team A. 500-day average reference line: highest for Team A. Days led: estimate about 300/500 for Team A.
  _ Calculations Estimations:
  Team A fulfills criteria 1 and 2, but not criterion 3. So, Team A earns exactly 2 points.
  _ Comparison to Answer Choices:
  Choices are 1, 2, or 3 points. 2 points is correct based on the approximation and the condensed solution.

FINAL ANSWER Blank 2: 2

Summary

Team A is the winner of the contest, earning 2 points: one for achieving the highest 500-day average and one for having its half-balance cross another team's full-balance at some point. Team A did not lead for 80% of the contest days, so it did not earn a third point.

Question Independence Analysis

The questions are dependent. The second blank requires knowing which team won (from the first blank) to determine how many points that winning team earned.
