7. In the following paragraph, there is a blank sentence. Choose from among the four options below, the most logically consistent sentence to fill this blank: Environmentalists, dismayed by the havoc that industrial human societies are wreaking on the earth, often hark back to a golden age when ancient human societies lived in harmony with nature.
It is now evident that the collapses of the Inca and Harappan civilization were correlated with environmental degradation, suggestive of expanding human populations outgrowing their
environments. Likewise, the extinctions of the magnificent mega-fauna of the new world
coincided with the arrival and migration of the first humans across the Americas. This recent
scientific evidence makes the supposed past Golden age of environmentalism look mythical.
How can we reconcile this evidence with stories of conservationist cultures from across the world?
a) Indeed, recent paleontological and archaeological studies are providing evidence for such a golden age.
b) However, recent paleontological and archaeological studies suggest the fossil records of human brain evolution that we had earlier may be inaccurate.
c) However, recent paleontological and archaeological studies are beginning to paint a very different picture of ancient human societies.
d) However, recent scientific studies are beginning to suggest that the environmental impacts of industrial societies are not significant.

5. Suppose there was a blood test for a fictitious disease called ‘tahr acrophobia’. The false positive rate for this test is 1 in 20. In other words, out of 20 non-diseased tahr that are tested, on average one will test positive, even though it does not have the disease. You test 20 nondiseased tahr for this disease.

6. You are interested in how growth rates of Teak trees are affected by their distance from road edges, and you think this effect is mediated by a fungal disease of Teak (called ‘mycoferous existentialitis’). By measuring infection intensity (in terms of percent trunk area covered by fungus) in trees at different distances (in metres) from road edges, you come up with this relationship:
Infection intensity = 40 – 0.5×Distance
Measuring growth rate is more difficult, and so, for a smaller set of trees you look at the relationship between infection intensity and growth rate (in cm of trunk diameter per year), and find this relationship:
Growth rate = 2 – 0.01×Infection Intensity
Assuming that nothing else affects infection or growth rate, what equation would predict the growth rates of Teak trees based on distance from road edge?
a) 40 – 0.5×Distance
b) 2 – 0.01×Distance
c) 0.8 + 0.05×Distance
d) 1.6 + 0.005×Distance
7. An ecologist measures a sample of lake water and finds 20 million Euglenoides (Euglena species) per cubic metre. This is a measure of:
a) Population size
b) Dispersion
c) Density
d) Carrying capacity
8. The ratio of population size in any given year divided by the population size the previous year is 1.1. If the starting population size is 80, then in 10 years what is the expected population size?
a) 80 × 101.1
b) 80 × 1.110
c) 10 × 801.1
d) 80 + 10 × e1.1
9. In order to determine the relationship between testosterone and aggression in lizards, a field biologist spends the summer measuring the percentage of time 10 males and 10 females spend fighting.
