The Correct Answer is D
Student's t-Tests
"Student" (real name: W. S. Gossett [1876-1937]) developed statistical methods to solve problems stemming from his employment in a brewery. Student's t-test deals with the problems associated with inference based on "small" samples: the calculated mean (Xavg) and standard deviation () may by chance deviate from the "real" mean and standard deviation (i.e., what you'd measure if you had many more data items: a "large" sample).

The correct Answer is C
'Vision 2020: The Right to Sight’ is a global campaign with the objective of liminating avoidable blindness by the year 2020. The World Health Organization (WHO) in collaboration with various international, non-governmental and private organisations launched it worldwide on February 18,1999.
Strategies for implementing Vision 2020
1. Control and prevention of major blinding diseases and disorders: Cataract, Trachoma, Onchocerciasis, Childhood Blindness, Refractive Errors and Low Vision have been identified as immediate priorities based on the burden of blindness they represent and the feasibility and affordability of interventions to prevent and treat them.

The correct Answer is C
What is glue ear?
Glue ear is a very common condition affecting children. It is also called ‘otitis media with effusion’, which means the middle ear contains fluid. It occurs when a sticky fluid (glue) builds up inside the ear. This can affect hearing because the parts of the middle ear cannot move freely, although the level of hearing loss is mild to moderate, rather than severe or profound.
If the child keeps having glue ear, Myringotomy with tube may be advised, where a ventilation tube called a grommet is inserted temporarily into the eardrum.
The Correct Answer is B
A grommet is a small bobbin-shaped tube used to keep open the incision made in the ear drum as a ventilation of secretory otitis media. It acts as a ventilation tube by allowing the Eustachian Tube to recover its normal function.
A period of watchful waiting is the best management strategy for children with otitis media with effusion. Grommets should only be considered for patients satisfying defined criteria. Patients and parents should be advised of the risk of potential harm e.g. tympanosclerosis.
The Correct Answer is C
Otosclerosis is a primary disease of the otic capsule and the ossicles. It is not known to occur outside the human temporal bone. It is characterized by a progressive hearing loss that may be conductive, sensorineural, or mixed. Histologically, it is seen as abnormal resorption and then deposition of bone in the labyrinthine capsule and middle ear. Otosclerosis is an important cause of auditory and, to a lesser extent, vestibular symptoms, and both can be treated effectively in most cases.
The correct answer is C.
If dihydropyridines are used alone, they may actually aggravate angina. Vasodilation caused by dihydropyridines is followed by a reflex increase in contractility and heart rate. Beta blockers are commonly given to combat such undesirable effects.
