3. A pattern of shapes is shown: ○ □ △ ○ □ △ ○ □ △. What is the 11th shape?
A. ○

The pattern repeats every 3: ○□△. Position 11: 11÷3 = 3 remainder 2... wait, 3×3=9, 10th=○, 11th=□. Hmm: position 1=○, 2=□, 3=△, 4=○... 11 mod 3 = 2, but we use 1-indexing: if remainder is 2, it's the 2nd in the pattern = □. But let me recount: 1=○, 2=□, 3=△, 4=○, 5=□, 6=△, 7=○, 8=□, 9=△, 10=○, 11=□. The 11th shape is □.
