Our Summary
The compass is an ancient navigational tool that uses the Earth's natural magnetic fields to help determine direction. The Earth's magnetic field is created by the movement of its liquid outer core, which has two poles: North and South. These magnetic poles are slightly different from the Earth's axis of rotation, which is used as the basis of the geographic poles. Compasses adjust for this difference, called declination, to serve as a valuable navigation tool. However, the magnetic North Pole shifts and changes over time, so compasses do not always point precisely towards the North Pole.
ENGLISH:
1. Select the option that corresponds to a 'feat'.
a) The diversion of traffic
b) A student's tribute to the mentor
*c) An acrobatic performance
d) The cancellation of a flight booking
In the passage, the achievement of major feats is mentioned as an example of the importance of compasses in navigation. A feat is a notable or impressive act or accomplishment, such as an acrobatic performance. Options a, b, and d are not feats.
2. The writer refers to the compass as a "key" breakthrough, to highlight its__________
*a) importance
b) scientific nature
c) ease of use
d) novelty
In the passage, the writer refers to the compass as a "key breakthrough" to highlight its significance in the history of navigation. The term "key" signifies that the compass was essential or crucial to the achievement of major feats such as the first transoceanic voyages and the circumnavigation of the globe. Options b, c, and d are not reasons why the compass is referred to as a "key" breakthrough.
3. Select the option that can be used, both as a noun as well as a verb, in the given form.
a) uniform, magnetic, point
b) Only uniform
c) uniform and core
*d) point, iron and core
Point, iron and core can all be used as a noun and a verb. For A, Magnetic isn't a verb. Uniform can be used as a verb. But D has all the elements.
4. Identify the meaning of the adjective in the given line from the TEXT..
"compasses at Greenwich pointed true north.'
a) aimed *b) precise c) topmost d) sharp
In the given line, the adjective "true" is used to describe the direction that the compasses at Greenwich pointed. In this context, "true" means correct, accurate, or exact. Options a, c, and d do not have the same meaning as "true" in this context
5. Which action suitably corresponds with 'undulates' ?
a) praying
b) walking a dog
c) sharing a secret
*d) dancing
The word "undulate" means to move with a smooth, wavelike motion. An action that suitably corresponds with this meaning is dancing, where the movement of the body is smooth and fluid. Options a, b, and c do not involve a wavelike motion.
LOGIC
Passage
5 towers made by civilisation X were declared to be protected heritage building. Uniquely,
four of them are placed geographically such that they are the vertices of a square. The fifth
is placed at the point of intersection of the two diagonals of the square. Let the towers be
named A, B, C, D and E. The following information is given to you about the five towers :
•-
i. C, A and B are in a straight line (in no particular order) that runs from south-east to north-west.
ii. If one looks directly east from B, no tower is visible. This is not true for A and D.
ili. If one looks directly north from D, a tower is visible.
1. Based on the above information, which tower is in the centre?
a) A
b) B
c) C
*d) Insufficient information
Based on the given information, it can be deduced that A, B, and C are in a straight line, along the diaginal. B is either in the middle or bottom right of the square. If If you look east from A there is a tower, so A is by default in the top left of the square (because if you look right you can see a tower). D has to bottom left, since bottom right is either B or C. Top right is only remaining E. So the only remaining piece in the puzzle is B and C's location - either middle or bottom right. So, the first answer is d - can be either.
If you're in the centre - and look directly east - you can't see a tower, and from the bottom right you can't see a tower either. So either case possible.
2. If one seeks to travel to D from A, one has to go
a) East b) South-east c) West to) **South
3. If one seeks to travel to B from A, one has to go
a) East to go
c) West
b) South-east
d) Cannot be determined
B is either in the middle, or bottom right - so from B to A is north west.. None of the answers are right
4. At sunset, A's shadow points
a) Towards B
b) Towards C
c) Towards D
*d) Towards E
Sunset means that the sun is in the west - so the shadow will fall on the opposite side. So the shadow is likely to fall towards E.
5. A compass (circular in shape) consists of two parts : a magnetic needle that points towards the magnetic north, and a circular piece of paper with directions written on it. If, somehow, the piece of paper rotates a quarter-circle counter-clockwise, which geographic direction does needle point towards ?
*a) Approximately east
b) Exactly east
c) Approximately west
d) Exactly west
Imagine the paper has North South East West Marked, and it is in line with the real needle. If the paper shifts, 1/4th lift, then North Shows to the left. Assuming this is the new north, the needle will be approx east. This question isn't really that clear about the dynamics of the paper. But such is life...
6. A is holding a compass at the time of sunrise. He points it towards the direction of the sunrise and sees that it reads "SW". This means that the compass has rotated
*a) 135 degrees counter-clockwise or 225 degrees clockwise
b) 135 degrees clockwise or 225 degrees counter-clockwise
c) 45 degrees clockwise or 315 degrees counter-clockwise
d) 45 degrees counter-clockwise or 315 degrees clockwise
The sun rises in the east. So East to South West is 135 degree counter clockwise. There is ambiguity here - the official says it's 135 clockwise - but right to left is counter :P
Don't know
7. In the facts of the question above, what actual direction is "NW" on the compass pointing towards ?
a) North *b) South c) East d) West
