  1. 1.) The correct answer is 48 over 7 (not listed). This is because if you need 7 gallons of fuel to plow 3 acres, then the MAXIMUM acrage you can plow on a full tank is a scale-up from 3 to 16/7 (the ratio of full tank fuel to 7 gallons) times the corresponding acrage at 7 gallons
    so acrage = (16/7) (3) = 48/7
    2.) Either B (valuable) or E (functional) should do, but I am leaning towards E (functional).
    3.) B. “involves”. Present tense verb for “Reading” since “Reading” is also present tense
    Hope that helps

  2. A gasoline tank on a certain tractor holds 16 gallons of gasoline. If the tractor requires 7 gallons to plow 3 acres, how many acres can the tractor plow with a tankful of gasoline?
    A. 66 over 7
    B. 71 over 6
    C. 71 over 3
    D. 102 over 3
    E. 371 over 3
    # acres = 16 * 3 / 7 = 48/7
    The answer is none of the available choices.
    Tantra paintings from India are not only beautiful but ——-: in addition to their aesthetic value, they are used to facilitate meditation.
    E. functional (the adjective, functional, corresponds to the phrase “they are used”)
    If you think the original phrasing produces a better sentence than any of the alternatives, select choice A. (Basically, which other word fits in better other than involve?)
    Reading maps involve several abilities, including the ability to locate places, to ascertain directions, to measure distances, and to interpret the mapmaker’s symbols.
    B. involves (the verb, involves, matches the singular noun, reading)

  3. 1) 6 6/7
    14 gallons can flow = 6 acres
    2 gallons can flow = 6/7 acres
    ( 7/3 = 2/x ==> 7x = 6 ==> x = 6/7)
    the answer is 6 and 6/7
    2) the correct word is functional.
    3) the correct word is involves. Reading is the subject which is singular.

  4. A gasoline tank on a certain tractor holds 16 gallons of gasoline. If the tractor requires 7 gallons to plow 3 acres, how many acres can the tractor plow with a tankful of gasoline?
    48/7 = 6.9 acres. This should be the answer.
    Seeing as the choices are only:
    A. 66 over 7 = 9.4
    B. 71 over 6= 11.8
    C. 71 over 3= 23.6
    D. 102 over 3= 34
    E. 371 over 3= 123
    I think that maybe it requires ‘acre’ to be changed to another unit that will fit to one of the answers above.
    Tantra paintings from India are not only beautiful but ——-: in addition to their aesthetic value, they are used to facilitate meditation.
    A. garish – showy
    B. valuable – precious
    C. numerous – many
    D. ornate- decorative
    E. functional-practical
    E, functional. Otherwise it wouldn’t mention ‘they are used to facilitate meditation.’
    Reading maps involve several abilities, including the ability to locate places, to ascertain directions, to measure distances, and to interpret the mapmaker’s symbols.
    A. involve
    B. involves
    C. will involve
    D. has involved
    E. have involved
    B. The word ‘maps’ isn’t the word that you use as basis. It is ‘reading’.
