Read the passage below and answer Question No. 61:

Taking a picture with a camera is making a decision about composition. It means how you
choose to frame the picture you're about to make. Many books have been written about
composition, and while no two people are likely to frame the same scene the same way, there
are some general guidelines that can help you improve your photos and make them better. First
you need to decide, while composing a picture, what your subject is. Of all the things you see in
front of you, which one is the reason for your taking the photo? Once you've answered that
question you can begin to work on how best to show that subject. The rule of thirds is a guide to
help you do just that. When you look through your viewfinder or at the LCD screen, imagine a
tic-tac-toe grid over the scene. These gridlines are a guide to help you frame your image and
won’t show up in your final picture. Notice where the lines intersect. The rule of thirds suggests
that these points are the best places to position your subject. Doing so will generally result in a
pleasant and balanced composition. Try moving your camera so your subject appears where two
of the lines meet. The subject doesn’t have to be directly on the intersection but somewhere
close to it. Try a couple of different compositions to find the one you like best. These same
gridlines can help you to keep your horizons level and the vertical elements in your photo
straight.

I. Using the rule of thirds, you can compose your picture:
i. as you wish
ii. similar to others
iii. that looks better

II. While composing a picture, first of all you decide:
i. the subject
ii. the composition
iii. the points of intersection on a tic-tac-toe grid

III. How many points are suggested by the rule of thirds to place your subject?
i. Nine
ii. Three
iii. Four

61. The correct answers to I, II and III are:
A. iii, iii, ii, respectively
B. i, ii, iii, respectively
C. iii, i, iii, respectively
D. ii, i, i, respectively 3 marks

Read the passage below and answer Question No. 62:

Over the last thirty years, there has been increasing scientific evidence that pets can help to
keep us fit and well. Pets can even help speed up recovery after major illness. A study found that
owning a pet produced improvements in general health in as little as one month. This continued
over the 10-month study. Pet owners were found to suffer fewer ailments, such as headaches,
colds and hay fever. Stroking a pet or simply watching a fish swim in an aquarium helps us to
relax. Indeed, the mere presence of a pet seems to have the same effect, reducing heart beat
rate and lowering blood pressure. Research has shown that this effect is particularly marked in
people suffering from high blood pressure. The reduction in blood pressure is equivalent to that
gained by eating a low salt diet or cutting down on alcohol consumption. Heart disease is one of
the UK's biggest killers, yet it is another area where pets provide health benefits. One study
showed that keeping a pet significantly reduced levels of cholesterol and blood triglyceride. This
fact, combined with the reduction in blood pressure from being with a pet, may make pet
owners less prone to heart attacks than non-pet-owners. Pet ownership proved to be one of the
best predictors of survival from a heart attack, according to an American study. The study
showed that those patients who owned a pet had a much better chance of surviving for more
than a year after a heart attack - a difference which could not be explained by the extra exercise
the pet owners enjoyed. Children who own pets are often less self-centred than those who do
not. Psychiatrically ill people were happier as a result of looking after a pet. Pets provide
companionship and promote a general feeling of well-being. For example, pets in residential
homes improve both patient and staff morale. Pets can lessen the feelings of isolation and
loneliness and provide a sense of purpose among elderly people. Having to make the effort to
care for a pet on a regular basis provides a feeling of fulfilment.

I. Owning a pet helps in ….....:
i. learning mathematics
ii. recovering from various disease
iii. making friends

II. Pet owners were found to suffer from ……...:
i. headache
ii. allergies
iii. don’t know

III. Pets can provide ……….:
i. lesser feeling of loneliness
ii. improved muscle mass
iii. both (i) and (ii)

62. The correct answers to I, II and III are:
A. iii, iii, i, respectively
B. ii, iii, i, respectively
C. ii, i, iii, respectively
D. ii, iii, iii, respectively 3 marks
