IPH EXERCISE

Exercise 4: Victoria University of Wellington has conferred an honorary degree on a distinguished astrophysicist in a recent graduation ceremony. Professor Warrick Couch ....1.... (was receiving / received / has received / is received) the honorary degree of Doctor of Science for his remarkable contribution to our knowledge of galaxies and dark energy. Professor Couch is a distinguished astrophysicist who has ....2.... (led / played / done / found) a crucial role in the discovery that the Universe is expanding at an accelerating rate, a finding which led to the lead scientists being awarded a Nobel Prize in Physics in 2011, which he attended in recognition of his contribution. In his research, Professor Couch uses large ground-based and spaced-based telescopes to observe galaxy clusters, ....3.... (who / they / those / which) are the largest Structures in the Universe. He is also involved in a number of national and international committees overseeing the management of these telescopes. ....4.... (As a result of / Instead of / In addition to / Regarding) his own research activities, Professor Couch has worked to support young researchers and provide public comment on astronomy internationally. #RWFIB #Apeuni_1 @Iran_pte_house

Exercise 3: Conservationists have long debated whether the koala should go on the Australian national threatened species list. ....1.... (But / While / Like / Because) the koala is clearly in trouble in some parts of the country – in Queensland, for example, high numbers ....2.... (have afflicted / are afflicted / are afflicting / afflicted) by disease – in other parts such as Victoria and South Australia the problem is not that koala populations ....3.... (are falling / are fallen / falls / fallen), but that they have grown to the point where they are almost too numerous. For a species to be classed as vulnerable, its population ....4.... (must have decreased / decreased / decrease / must decrease) by more than 30 percent over the last three generations or 10 years. The problem is that when such a stipulation is applied to koalas, the Victorian boom offsets the Queensland bust, and the species stays off the list. This has repercussions because northern koalas are different to southern ones. They are smaller, for example, and they contain a genetic ....5.... (expansion / extension / explanation / variation) not represented in the South. ....6.... (Nonetheless / For example / As an addition / For this reason), a split listing has been devised koalas from New South Wales, the ACT and Queensland are now officially 'Vulnerable'; those from Victoria and South Australia are not considered threatened. #RWFIB #Apeuni_273 @Iran_pte_house

Exercise 2: The heart functions as a pump at the centre of the circulatory system. In humans it is located in the chest cavity, between the lungs, ....1.... (compared / rather than / a bit / less than) to the left. The heart consists of four chambers surrounded by a very strong muscular wall, the myocardium. The upper chambers, the right and left atria, ....2.... (lower / receive / repel / transfer) blood entering the heart, and the lower chambers, the right and left ventricles pump the blood out of the heart, via the pulmonary and the systemic circulatory systems. The two systems work as ....3.... (well / followed / follows / follow). Blood from the body enters the right atrium, ....4.... (being / is / has / had) passed into the right ventricle and from there is propelled through the pulmonary artery to the lungs. In the lungs the blood releases carbon dioxide and absorbs oxygen and is then ....5.... (transporting / transported / transport / having transported) back to the heart into the left atrium. From here it passes into the left ventricle, which pumps the oxygenated blood around the body. #RWFIB #Apeuni_404 @Iran_pte_house
