must come fifth and seventh, to avoid violating rule 1. Since Lohan cannot be seventh due to
rule 6, that means Angelina must arrive seventh (c).

Questions 4 - 5 are based on the following information:
Modern technology has the potential to alter the composition of the current population with
respect to age, polymorphism and genotype. Technology, including efficient and affordable
air travel, medical advances and genetic engineering, has had and will continue to have a
profound impact on the human population.
Historically, geographical barriers have limited interbreeding between cultural groups and
promoted the formation of human polymorphism. With improved access to air travel and
internet communication, humans have become more mobile and as a result polymorphism has
become less common. Medical advances such as vaccinations and gene therapy will support
an increased life expectancy and as a result, an aging population.
4. According to the passage, modern technology has had a significant impact on:
Human population numbers.
Human cultural mixing and breeding between cultural groups.
, Immunity to infectious diseases through vaccination.
The amount of pollution in the air as a result of air travel.
Correct Answer: B
Explanation:
The passage talks about the reduction of polymorphism due to cultural mixing (b). The size
of the human population (a), immunity to diseases (c), and pollution (d) are not discussed.

5. The main point of the passage is:
The determining role of technology in human society.
The important contribution of technology to the increasing globalization.
The ability of science to increase the population.
The ability of technology to alter the genetic and cultural constituency of humanity.
Correct Answer: D
Explanation:
The passage lists many ways in which technology affects the age, polymorphism and
genotype of the human population (d). This is not necessarily the determining role of
technology (a). Although increasing globalization is attributable to technology, that is not the
main point (b). The size of the human population is not mentioned (c).
