I posted this test on another forum and I thought I would post it here also. Have at it. You remember those test questions in grade school? You know the question where you drew a line from an item in column 1 to the matching item in column 2. So here is the question can you draw a line from Group A, Group B or Group C to the matching item in one of the other groups? GROUP A WDDO-001, DDO-001, 1-O-IV, FS-01.012.00, 1DO-001, CDDO-001, B-2053 WDDO-002, DDO-002, 2-O-VI, FS-01.012.10, 1DO-002 WDDO-003 WDDR-001, DDR-001, 1-R-II-C, - I think this matches 1DR-001 in Group C WDDR-002, - I think this matches 1DR-002 in Group C WDDR-003 WDDR-004 WDDR-005, DDR-005, 5-R-VI WDDR-006 WDDR-007 WDDR-008 WDDR-009 WDDR-010 WDDR-011 WDDR-012 WDDR-013 WDDR-014 WDDR-015 WDDR-016 WDDR-017 GROUP B DDR-002, 2-R-VI DDR-003, 3-R-IV+VIII DDR-004, 4-R-VI DDR-006, 6-R-VI DDR-007, 7-R-II+VI DDR-008, 8-R-VI DDR-009, 9-R-II-V+VI DDR-010, 10-R-VI DDR-011, 11-R-II-C+VI GROUP C 1DR-001, - I think this matches WDDR-001 in Group A ??? 1DR-002, - I Think this matches WDDR-002 in Group A ??? 1DR-003 1DR-004 1DR-005
