Which construct explains a person’s belief that using condoms will reduce the risk of HIV infection?

Scenario: Rural Northern Cape: Alcohol Reduction and Health Behaviour ChangeIn a small farming community in the Northern Cape, hazardous alcohol consumption is a growing public health concern, particularly among men aged 25–45. Many individuals engage in regular binge drinking over weekends, contributing to increased rates of interpersonal violence, road accidents, and poor adherence to chronic medication such as hypertension treatment.A local primary healthcare clinic has introduced a behaviour change programme based on the Transtheoretical Model to support individuals in reducing alcohol consumption. The programme includes counselling sessions, peer support groups, and community awareness campaigns.During implementation, healthcare workers observe the following:Some individuals do not see their drinking as a problem and avoid attending sessions.Others acknowledge the risks but feel unmotivated to change.A few have started reducing their alcohol intake but struggle with relapse during social gatherings.Some participants actively attend support groups and report sustained behaviour change.

The graph below shows the stress–strain behavior of two random human tissues (A and B) under tensile loading. Which of the following assumptions is most likely to be true?  

Data from a uniaxial tension test to failure for a human cortical bone specimen are given below. Data point 4 corresponds to failure.  Estimate the Young’s modulus, yield stress, and ultimate stress 

  Young Modulus  Titanium  380 MPa  Bone  500 MPa  Cartilage  900 MPa  Ligament  1000 MPa  A titanium biomedical device transfers a force of 1200 N over a 10 mm2 area of a femur. It is known that in a normal femur joint the weight of 90kg is transmitted to the bone through the same 10mm2 area. Which situation presents the greatest strain on the femur bone? 

Which parameter BEST describes the energy absorbed before bone fracture? A. StiffnessB. ToughnessC. Yield strengthD. Elastic modulus Give the right answer option A, B, C or D

Which curve indicates brittle fracture behavior? [Option]
