• A)Russian speakers took longer than did English speakers to make this determination when one comparison stimulus was dark blue and the other comparison stimulus was light blue.
• B)English speakers took longer than did Russian speakers to make this determination when one comparison stimulus was dark blue and the other comparison stimulus was light blue.
• C)Russian speakers took longer than did English speakers to make this determination when all three stimuli were shades of light blue.
• D)English speakers took longer than did Russian speakers to make this determination when all three stimuli were shades of light blue.
