Reading Comprehension - Test - 6

Passage # 1:
In addition to practical reasons for using brick as the principal construction material, there was also an ideological reason, Brick represented durability and permanence. The Virginia Company of London instructed the colonists to build hospitals and new residences out of brick. In 1662, the Town Act of the Virginia Assembly provided with the approval for the construction of thirty two buildings and prohibited the use of wood as a construction material. Had this law ever been successfully enforced, Jamestown would have been a model city: Instead, the residents failed to comply fully with the law and by 1699 Jamestown had collapsed into a pile of rubble with only three or four habitable houses.

1. It can be inferred from the passage that settlers who built with bricks in the 1660's were
    A. planning to return to England
    B. obeying the law
    C. not concerned about durability
    D. interested in larger residences

2. According to the passage, what eventually happened to Jamestown?
    A. It was practically destroyed
    B. It became a medical city.
    C. It remained the seat of government.
    D. It was almost completed. .

Passage # 2:
If one were to ask a group of randomly selected individuals to define "price," many would reply that price is an amount of money paid by the buyer to the seller of a product or service or, in other words, that price is the money value of a product or service as agreed upon in a market transaction. This definition is of course, valid as far as it goes. For a complete understanding of a price in any particular transaction, much more than the amount of money involved must be known. Both the buyer and the seller should be familiar with not only the money amount, but also with the amount and quality of the product or service to be exchanged, the time and place at which the exchange will take place and payment will be made, the form of money to be used, the credit terms and discounts that apply to the transaction, guarantees on the product or service, delivery terms, return privileges, and other factors. In other words, both buyer and seller should be fully aware of all the factors that comprise the total "package" being exchanged for the asked-for amount of money in order to evaluate a given price.

3. According to the passage, which of the following is NOT a factor in the complete understanding of price?
    A. Instructions that come with a product
    B. The quantity of a product
    C. The quality of a product
    D. Warranties that cover a product

4. In the last sentence of the passage, the word "they" refers to
    A. return privileges
    B. all the factors
    C. buyer and seller
    D. money

5. The paragraph following the passage most likely discusses
    A. unusual ways to advertise products
    B. types' of payment plants for service
    C. theories about how products affect different levels of society
    D. how certain elements of a price "package" influence its market value

Passage # 3:
The apparent brightness of a star as we see it from the Earth is its apparent magnitude (m). A fairly bright star such as Aldebaran is of first magnitude (i.e. has = 1), a rather fainter one such as the polestar has m = 2 and so on. The faintest star visible to the naked eye has m = 6, and is 100 times fainter than a star of m = 1. The faintest detectable stars have m = 23. At the other end of the scale, stars brighter than first magnitude can have m = 0(e.g. Alpha Centauri) or even minus values, such as Sirius with m = -1.5. The Sun has m = -26. A star's apparent magnitude depends upon both its real brightness and its distance from us. It can happen that a star which is really very luminous can appear faint simply because it is far away. To compare the real brightness of stars, astronomers use absolute magnitude (M), this is the apparent magnitude a star would have if placed at a standard distance from the Earth of 32.6 light years. The Sun has M = 4.8 while Aldebaran has M = 0.1. Aldebaran is thus inherently nearly 100 times more luminous than the Sun.

6. In terms of apparent brightness, which of the following lists of stars is in the correct order from faintest to brightest?
    A. The polestar, Aldebaran, Alpha Centauri, Sirius
    B. Aldebaran, the polestar, Alpha Centaur;, Sirius
    C. Sirius, Alpha Centauri, the polestar, Aldebaran
    D. Sirius, Alpha Centauri, Aldebaran, the polestar

7. A star with an apparent magnitude of m = 16
    A. large and bright
    B. small, but visible to the unaided eye
    C. visible only through a telescope
    D. completely invisible

8. Which of the following would be observed by someone on Earth looking with unaided eyes in the direction of two stars, one with m = 1 and one with m = 5?
    A. one visible star
    B. two stars of approximately equal brightness
    C. two stars, one a great deal brighter than the other
    D. two stars, one slightly brighter than the other

9. Which of the following questions do scientists answer by comparing the absolute magnitude of two stars?
    A. which star is farther away?
    B. which star is really more luminous?
    C. which star can be seen by the naked eye?
    D. which star is closer to being 32.6 light years away?

10. This passage would most likely be assigned reading in a course in
    A. astronomy
    B. geography 
    C. astrology
    D. electrical engineering
