Circle the molecule that is a stronger acid. Briefly explain your choice. Use structures to support your reasoning. 

**Chemical Structures**

The image displays the structural formulas of two chemical compounds, both derivatives of benzoic acid with variations in their functional groups.

**Left Structure:**
- **Chemical Name:** 4-(Dimethylamino)benzoic acid
- **Description:** 
  - The central structure is a benzene ring with three double bonds.
  - Attached to the fourth carbon of the benzene ring is a carboxylic acid group (–COOH).
  - At the para position (opposite to the carboxylic group) is a dimethylamino group (–N(CH₃)₂), indicating nitrogen bonded to two methyl groups (\-CH₃).

**Right Structure:**
- **Chemical Name:** 3-(Dimethylamino)benzoic acid
- **Description:**
  - This structure features a benzene ring at its core with alternating double bonds.
  - A carboxylic acid group (–COOH) is attached directly to the benzene ring.
  - The dimethylamino group (–N(CH₃)₂) is positioned at the meta location, relative to the carboxylic acid group.

These chemical structures are important in understanding the impact of functional group positioning on the properties and reactivity of benzoic acid derivatives.
