The poem is a tribute to the poet’s mother. She is looking at an old photograph of her mother which has a frame of cardboard. The picture has three girls in which the middle one is the oldest and tallest.
It is her mother when she was twelve years old or so. Beside her, on both sides are her two cousins, Betty and Dolly, who are holding her hands and are younger than her. They went for paddling on a beach holiday. Her uncle took the photograph then. The poet could not help but notice her mother’s sweet face. The sea touched her terribly transient feet which depicted that she changed over the years and the sea remained the same.
After twenty-thirty years, her mother would laugh at the photograph. She would make the poet look at the photograph and tell her how their parents would dress them up for the beach holiday. The beach holiday was her mother’s favourite past memories while her laugh was the poet's favourite memory. Both of them lost something which they cherished a lot and yet cannot live that moment again.
Those sweet moments were memories now.
Now, the poet’s mother had been dead for the past twelve years, which is the same number as of her age when the photograph was taken back then. She cannot express the grief that she has from her mother’s absence.

DISORDERS OF RESPIRATORY SYSTEM
- Asthma is a difficulty in breathing causing wheezing due to inflammation of bronchi and bronchioles.
- Emphysema is a chronic disorder in which alveolar walls are damaged due to which respiratory surface is decreased.
- Occupational respiratory disorders include lung damage due to inflammation, which ultimately leads to fibrosis.

The dimensional formula of gravitational constant is given by,
M-1 L3 T-2
Where,
- M = Mass
- L = Length
- T = Time
Derivation
From Newton’s law of gravitation,
Force (F) = [GmM] × r-2
Gravitational Constant (G) = F × r2 × [Mm]-1 . . . . (1)
Since, Force (F) = Mass × Acceleration = M × [LT-2]
∴ The dimensional formula of force = M1 L1 T-2 . . . . (2)
On substituting equation (2) in equation (1) we get,
Gravitational Constant (G) = F × r2 × [Mm]-1
Or, G = [M1 L1 T-2] × [L]2 × [M]-2 = [M-1 L3 T-2].
Therefore, the gravitational constant is dimensionally represented as M-1 L3 T-2.

Mr Crocker-Harris appears as a stem master who is a man of principles and stickler to the rules. He believes in fair assessment of his students and is not swayed by emotions, as the man is hardly human. He is not a sadist, but strict in performance of his duties. He is a man of strict behavior, rules, and principle. He gives priorities to his work rather than thinking about the views of the people. He gives a fair evaluation of his students and never steps backward while performing his duties. Even on his last day at school, when he is over-busy in his own affairs, he does not neglect his duty towards his students.

The present set up of the Long Form of the Periodic Table can accommodate at the maximum 118 elements. After this, according to Aufbau principle, 8.y-orbital should be filled. Therefore, the outer electronic configuration of element having atomic number 119 will be 8s1. Since it has one electron in the outermost s-orbital, its valency will be 1 and it should belong to group 1 along with alkali metals. The general formula of its oxide will be M20, where M represents the element.

In spite of natural fertility, agriculture was the subject to hazards because:
- River Tigris was overflowed during the particular month of a year.
- The river often changed its course which causes water scarcity in a particular region.

The dimensional formula of coefficient of friction is given by,
[M0 L0 T0]
Where,
- M = Mass
- L = Length
- T = Time
Derivation
Coefficient of friction (μ) = Frictional Force × [Normal Force]-1 . . . . (1)
Since, Force (F) = Mass × acceleration = Mass × velocity × [Time]-1
And, velocity = Displacement × [Time]-1
∴ The dimensions of Force = [M] × [LT-1] × [T]-1 = [M1 L1 T-2] . . . . (2)
On substituting equation (2) in equation (1) we get,
Coefficient of friction (μ) = Frictional Force × [Normal Force]-1
Or, μ = [M1 L1 T-2] × [M1 L1 T-2]-1 = [M0 L0 T0].
Therefore, the coefficient of friction is dimensionally represented as [M0 L0 T0].
