Explanation:

Question 7: Personality disorders are classified into clusters. Cluster B includes antisocial, borderline, histrionic, and narcissistic personality disorders. Paranoid is in Cluster A, avoidant and dependent are in Cluster C.
Question 8: Myopia (nearsightedness) is corrected with concave lenses as they diverge light rays. Presbyopia, an age - related loss of near - focusing ability, is corrected with convex lenses which converge light rays. Emmetropia is normal vision, diplopia is double vision.
Question 9: The suffix "-oma" means tumor. "Neur-" relates to nerve. So, neur/oma is a tumor made up of nerve cells. "Poly/neur/itis" is inflammation of many nerves, "cerebr/al thromb/o/sis" is a blood clot in the brain, "en/cephalo/malacia" is softening of the brain.
