Read the passage below and determine which combination of the proposed statements serves as a suitable course(s) of action. Passage: An operational audit of the public transit network in the municipality of Vidanpur has revealed that while total commuter ridership has increased by 25% since the introduction of an all-digital smart-card ticketing system, the usage of transit services by disabled commuters has fallen by 40% over the same period. Feedback from local advocacy groups indicates that the touchscreen interfaces on the ticketing kiosks are mounted too high for wheelchair users to reach, and the mobile application lacks audio-guided navigation for visually impaired passengers. Furthermore, many individuals noted a complete lack of tactile ground indicators leading up to the new automated turnstiles. Statements (Proposed Courses of Action): 1. The transit authority should introduce software updates to integrate comprehensive audio-guided navigation features within its mobile application. 2. The transit authority should completely dismantle the digital smart-card ticketing system and return to manual paper ticketing collected by conductors to ensure immediate accessibility for everyone. 3. The transit authority should modify a designated number of ticketing kiosks to lower their screens and install tactile ground indicators leading up to the automated turnstiles.
