Question 1
Flag this item
In the Mohs scale for the hardness of minerals, a mineral will scratch only those below it on
the scale (i.e. those with a higher number will scratch any with a lower number).
Human fingernail has a hardness of about 2.5.
The mineral acerite scratches fingernail but does not scratch orthoclase.
The mineral georgite is scratched by acerite, but not by fingernail.
10 DIAMOND
9 CORUNDUM
8 TOPAZ
7 QUARTZ
6 ORTHOCLASE
5 APATITE
4 FLUORITE
3 CALCITE
2 GYPSUM
1 TALC
1. This means that:
2.
georgite will scratch calcite but will not scratch apatite.
apatite may be harder than georgite but softer than acerite.
calcite may be harder than acerite but softer than georgite.
if georgite scratches fluorite it will scratch apatite.
Correct Answer: B
Explanation:
The mineral acerite scratches fingernail but does not scratch orthoclase. Therefore, the order
is:
Orthoclase
Acerite
Fingernail
The mineral georgite is scratched by acerite, but not by fingernail. Therefore, the order is:
Acerite
Georgite
, Fingernail
Combining both the possible order is:
Orthoclase (6)
Acerite
Georgite
Fingernail (2.5)
Acerite and Georgite carries values between 2.5 to 6
Calcite, Flurite and Aptite may have a value lower than or higher than Acerite and Georgite.
Hence the most appropriate answer is Apatite may have a value between Georgite and
Acerite. All other options which uses “will” is wrong.
Question 2

In a study carried out in London, saliva samples were taken from volunteers every hour
throughout the day from the time they awoke. It was found that the amount of cortisol, a
hormone associated with high stress levels, was significantly higher in each sample taken
from the volunteers who woke early (before 7:30 am) than in the samples of those who woke
late (after this time). The volunteers had been free to wake at a time that they liked and all
had slept for similar numbers of hours.
2. Which of the following is least supported by these
findings?
3.
A high level of cortisol causes people to wake early.
The fear of waking late raises cortisol levels.
Waking early causes high cortisol levels.
Waking late increases cortisol levels.
Correct Answer: D
Explanation:
Least supported is option D as it says that waking late increases cortisol which is
contradictory to the findings that show that the level of cortisol is high among those who
wake up early.

Questions 3-7 refer to the following passage:
The following passage is from a novel. Nazneen has recently come to London from a
, Bangladeshi village as part of an arranged marriage with a man twenty year’s older, named
Chanu. Here, her friend Rozia Is visiting Nazneen at her home, and they have been chatting
about some mutual acquaintances. Razia then asks Nazneen about her husband.
'Any news of the promotion?’ asked Razia.
'My husband says they are racist, particularly Mr. Dalloway. He thinks he will get the
promotion, but it will take him longer than any white man. He says that if he painted his skin
pink and white then there would be no problem.’ Chanu had begun, she had noticed, to talk
less of promotion and more of racism. He had warned her about making friends with ‘them’,
as though that were a possibility. All the time they are polite. They smile. They say please'
this and 'thank you' that. Make no mistake about it, they shake your hand with the right, and
with the left they stab you in the back.
‘Well,’ said Razia, 'this could be true.'
Nazneen turned the words over. This could be true. She waited for more. Razia was
unpicking a thread from her jumper,
Nazneen said, 'My husband says it is discrimination’.
'Ask him this, then. Is it better than our own country, or is It worse? If it is worse, then
why is he here? If it is better, why does he complain?'
These were questions she had neither asked nor thought of asking. She was in this country
because that was what had happened to her. Anyone else, therefore, was here for the same
reason.
'I don’t know if he complains; Nazneen found herself saying, 'He just likes to talk about
things. He says that racism is built into the “system", I don't know what "system” he means
exactly.'
'My son's teacher, she's a good one,’ said Razia. 'She helps him a lot, and he likes her. My
husband has a work colleague, he gives us things, Clothes that his children have grown out
of. A machine for drying hair, A radio and stepladders. All sorts of things. There are good
ones, and bad ones. Just like us. And some of them you can be friendly with. Some aren’t so
friendly. But they leave us alone, and we leave them alone. That's enough for me.
3. Judging by her response, Nazneen regarded Razia’s
question (line 1) as
4.
rude.
trivial.
appropriate.
unexpected.
Correct Answer: C
Explanation:
, It is an appropriate question since the two friends are meeting to chat about mutual
acquaintances and it is natural to ask about her husband’s promotion news

4. Nazneen’s comment ‘My husband says it is
discrimination’ (line 14) seems mainly intended to
5.
defend her husband.
criticize her husband.
