Question 11042

Which principle of design is demonstrated when a building's left half is a mirror image of its right half?

Rhythm
Bilateral symmetry✔️
Radial balance
Contrast

Correct Answer Logic:

Bilateral symmetry (also called axial or mirror symmetry) means one half of the composition is the mirror image of the other about a central axis.

Examples in architecture: Taj Mahal (bilateral symmetry on all four sides), most classical Greek temples, and many government buildings.

Other design principles: Rhythm = repetition of elements creating movement. Radial balance = elements arranged around a central point. Contrast = juxtaposition of opposing elements (light/dark, old/new).

Mathematics QUESTION #4099

Question 11045

On the contour segment from $A=(0+i)$ to $B=(1+i)$ (where $y=1$, $x:0\to1$, $dZ=dx$), with $f(Z)=y-x-3ix^2$, the contribution to the contour integral is:

$\dfrac{1}{2}-i$✔️
$-\dfrac{1}{2}+i$
$1-i$
$\dfrac{1}{2}-\dfrac{i}{2}$

Correct Answer Logic:

On $AB$: $y=1$, $Z=x+i$, $dZ=dx$, $f=1-x-3ix^2$. Integral: $\int_0^1(1-x-3ix^2)dx = \left[x-\dfrac{x^2}{2}-ix^3\right]_0^1 = 1-\dfrac{1}{2}-i = \dfrac{1}{2}-i$.

Retina✔️
Iris
Choroid
Sclera

The retina also contains bipolar cells, ganglion cells, and other neurons that process visual information before transmitting it via the optic nerve to the brain. The choroid provides blood supply; the sclera is the tough outer protective coat; the iris controls pupil size.
