plz answer these questions
1.hydroquinone (in developing solution) is
1. oxidizing agent
2. Reducing agent
2.All of the following statements related to RPI clasp assembly are false except one. which one?
1. The rest may be placed on the distal aspect of the occlusal surface
2.A boxlike rest seat is desirable to promote stability of prosthesis
3.Proper depth of rest seat may require a amalgam or direst filling gold restoration
4.Contact between the mesial minor connector and the adjacent tooth is desirable
3.which of the following is not avalid criterion of incisal reat seat design?
1.The deepest portion meaidistally is toward the centre of the tooth
2. sharp line angles are desirable
3.contact areas is involved in preperation
4.Small bevel is placed labially and lingually
5. 1 and 4
6.2 and 3
4. When surveying a diagonstic cast the selection of suitable anterioposterior tilt is to
1 indicate the greatest available support for the RPD
2. provide relative parallelism among the proximal tooth surface
3.provide suitable reciprocation for retentive clasp arms
4. eliminate soft tissue undercuts in retromylohyoid areas
5. which of the following staements regarding the design of minor connector is true
1.the minor connector must be rigid
2.the minor connector must engage an undercut
low to the tooth
3. the minor connector should present minimal interference to the tongue
4. the minor connector should cover the minimum of gingival tissue possible
5. 1,3 and 4
6. all the above
