Oh ok, my bad, I understand my mistake ! Thanks for your help

There is no issue, you're confusing the log you see, it is the input of the next test. The log appears above the test result.

There is an issue in Ruby.
Tests are :
Test.assert_equals(openOrSenior([[45, 12],[55,21],[19, -2],[104, 20]]),['Open', 'Senior', 'Open', 'Senior'])
Test.assert_equals(openOrSenior([[3, 12],[55,1],[91, -2],[54, 23]]),['Open', 'Open', 'Open', 'Open'])
Test.assert_equals(openOrSenior([[59, 12],[55,-1],[12, -2],[12, 12]]),['Senior', 'Open', 'Open', 'Open'])
Test.assert_equals(openOrSenior([[16, 23],[73,1],[56, 20],[1, -1]]),['Open', 'Open', 'Senior', 'Open'])

But for the number 3 : Test.assert_equals(openOrSenior([[59, 12],[55,-1],[12, -2],/!\issue => [12, 12]]),['Senior', 'Open', 'Open', 'Open'])
data[3][0] return 68 instead of 12
data[3][1] return 7 instead of 12
