In each of these questions, two statements I & II are given. These may have a cause and effect relationship or may have independent causes or be the effects of independent causes. Read the statements and mark answer as
Statement I: British surgeons have carried out what they claim is the world’s first lung transplant on a 20 year-old woman patient Becky Jones who was suffering from two fungal conditionsin the lungs.
Statement II: Lung transplant patients have never before beenable to have the transplant operation while suffering from aspergillus and multiple fungal balls. Jones is in perfect health and is able to breath freely again.
Both statements elaborate upon the rarity of this transplant but do not show any sign of being in a causal relationship. They probably are effects of a common cause (surgery or illness).
