Correct Answer: A

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: D

Rationale: Simple squamous epithelial tissue is the correct answer because it consists of a single layer of flat cells, which is characteristic of the tissue shown in Figure 1. This type of tissue is found in areas where rapid diffusion or filtration is required, such as the lining of blood vessels and the alveoli of the lungs. Its thin structure allows for efficient exchange of gases and nutrients.

Correct Answer: B

Rationale: Lower motor neuron is the correct answer because damage to these neurons directly affects the muscles they innervate, leading to atrophy, weakness, and loss of reflexes. This occurs due to the disruption of the neural connection between the spinal cord and the muscle, resulting in denervation and subsequent muscle wasting.

Correct Answer: A

Rationale: Speech is the correct answer because dysphasia refers to a language disorder that affects the ability to produce or comprehend spoken or written language. It is typically caused by damage to the language centers of the brain, such as Broca's or Wernicke's areas, and results in difficulties with communication.

Correct Answer: B

Rationale: Black substance (substantia nigra) is the correct answer because Parkinsonism is characterized by the degeneration of dopaminergic neurons in the substantia nigra. This leads to the classic symptoms of tremor, bradykinesia, and rigidity due to the loss of dopamine in the basal ganglia, which regulates movement.
