English Literature QUESTION #10714

Bilfor Evans
Mary Ann Evans✔️
T.S. Eliot
Emily Dickinson

Correct Answer Logic:

George Eliot was the pen name of Mary Ann (Mary Anne / Marian) Evans (1819–1880). She adopted a male pseudonym to ensure her works were taken seriously in an era when women writers were often dismissed or marginalised. Her major novels include Middlemarch, The Mill on the Floss, Silas Marner, and Adam Bede.

Chemistry QUESTION #5563

Question 4542

The thiol (–SH) functional group is present in which amino acid?

Cystine
Cysteine✔️
Methionine
Cytosine

Correct Answer Logic:

Cysteine is an amino acid with the structure $HSCH_2CH(NH_2)COOH$ — it contains a free thiol (–SH) group. Cystine is formed by oxidative coupling of two cysteine molecules (disulphide bond, –S–S–). Methionine contains a thioether (–S–) group, not a free –SH. Cytosine is a nucleobase, not an amino acid.

Mathematics QUESTION #11228

Question 4546

The solution set of $\sin x\cos x = \dfrac{\sqrt{3}}{4}$ is:

$\left\{\dfrac{\pi}{6}+n\pi\right\}\cup\left\{\dfrac{\pi}{3}+n\pi\right\}$
$\left\{\dfrac{\pi}{3}+2n\pi\right\}\cup\left\{\dfrac{2\pi}{3}+2n\pi\right\}$
$\left\{\dfrac{\pi}{6}+2n\pi\right\}\cup\left\{\dfrac{5\pi}{6}+2n\pi\right\}$
$\left\{\dfrac{\pi}{12}+n\pi\right\}\cup\left\{\dfrac{5\pi}{12}+n\pi\right\}$✔️

Correct Answer Logic:

$\sin x\cos x = \dfrac{\sqrt{3}}{4} \Rightarrow \dfrac{\sin 2x}{2} = \dfrac{\sqrt{3}}{4} \Rightarrow \sin 2x = \dfrac{\sqrt{3}}{2}$. So $2x = \dfrac{\pi}{3}+2n\pi$ or $2x = \pi-\dfrac{\pi}{3}+2n\pi = \dfrac{2\pi}{3}+2n\pi$. Thus $x = \dfrac{\pi}{6}+n\pi$ or $x = \dfrac{\pi}{3}+n\pi$... Hmm, or $x = \dfrac{\pi}{12}+n\pi$ or $x = \dfrac{5\pi}{12}+n\pi$. Dividing by 2: $x = \dfrac{\pi}{6}+n\pi$ or $x=\dfrac{\pi}{3}+n\pi$. Per key: option (A).

Mathematics QUESTION #6970

Question 4547

The integral $\displaystyle\int\dfrac{2x^{12}+5x^9}{(x^5+x^3+1)^3}\,dx$ equals (where $C$ is an arbitrary constant):

$\dfrac{x^{10}}{2(x^5+x^3+1)^2}+C$✔️
$\dfrac{x^5}{2(x^5+x^3+1)^2}+C$
$\dfrac{-x^{10}}{2(x^5+x^3+1)^2}+C$
$\dfrac{-x^5}{(x^5+x^3+1)^2}+C$

Correct Answer Logic:

Divide numerator and denominator by $x^{15}$:

$\displaystyle\int\dfrac{2x^{-3}+5x^{-6}}{(1+x^{-2}+x^{-5})^3}\,dx$

Let $t=1+x^{-2}+x^{-5}$. Then $dt=(-2x^{-3}-5x^{-6})dx$, so the numerator (divided by $x^{15}$) gives $-dt$:

$=-\displaystyle\int\dfrac{dt}{t^3} \cdot \dfrac{1}{x^{15}/x^{15}}$

Wait — let me redo with $t = x^{-5}+x^{-3}+1$... Actually substituting directly: $t=1+x^{-2}+x^{-5}$, $-dt=(2x^{-3}+5x^{-6})dx$.

Integral $= -\int t^{-3}dt = \dfrac{1}{2t^2}+C = \dfrac{x^{10}}{2(x^5+x^3+1)^2}+C$

Question 4553

Which one can be considered as living characteristics of a virus?

Can replicate itself✔️
No cellular respiration
Enzyme-less biochemistry
Lack of cytoplasm

Correct Answer Logic:

The primary living characteristic of viruses is their ability to replicate (reproduce) — albeit only inside a living host cell. Viruses contain genetic material (DNA or RNA) and direct the host's cellular machinery to produce new virus particles. All other listed options (no respiration, no enzymes, no cytoplasm) are non-living characteristics.

Tourism & Hospitality Management QUESTION #1637

Question 4554

The Tourism Marketing course discusses 'strategic alliances in the world airline industry' as referenced in the recommended readings. In the context of tourism marketing, such alliances primarily benefit tourists by offering which advantage?

Higher ticket prices through reduced competition
Seamless connectivity, code-sharing, reciprocal frequent flyer benefits, and expanded route networks that reduce the complexity and cost of international travel✔️

Electrical Engineering QUESTION #2173

Question 4556

A half-wave dipole antenna has $R_{rad} = 73\,\Omega$, $R_{loss} = 7\,\Omega$, and directivity $D = 1.64$. Its radiation efficiency and gain are:

$\eta = 91.25\%$, $G \approx 1.497\,(1.75\,\text{dBi})$✔️
$\eta = 80\%$, $G = 1.31$
$\eta = 100\%$, $G = 1.64$
$\eta = 50\%$, $G = 0.82$

Correct Answer Logic:

$\eta = \frac{73}{73+7} = 0.9125 = 91.25\%$. $G = \eta \cdot D = 0.9125 \times 1.64 \approx 1.497 \approx 1.75\,\text{dBi}$.

Reading and Writing (Module-1) QUESTION #5402

Question 4557

The following text is from Ezra Pound's 1909 poem "Hymn III," based on the work of Marcantonio Flaminio. As a fragile and lovely flower unfolds its gleaming foliage on the breast of the fostering earth, if the dew and the rain draw it forth; / So doth my tender mind flourish, if it be fed with the sweet dew of the fostering spirit, / Lacking this, it beginneth straightway to languish, even as a floweret born upon dry earth, if the dew and the rain tend it not. Based on the text, in what way is the human mind like a flower?

It becomes increasingly vigorous with the passage of time.
It draws strength from changes in the weather.
It requires proper nourishment in order to thrive.✔️
It perseveres despite challenging circumstances.

Correct Answer Logic:

The text compares a flower needing water to the mind needing spiritual nourishment, both requiring proper feeding to flourish rather than languish.

Mathematics QUESTION #4125

Question 4558

For $f(z) = \frac{1}{z}$, writing $z = re^{i\theta}$, the Cauchy-Riemann equations in polar form are satisfied when:

$u_r = \frac{1}{r}v_\theta$ and $v_r = -\frac{1}{r}u_\theta$
$u_r = \frac{1}{r}u_\theta$ and $v_r = \frac{1}{r}v_\theta$
$ru_r = v_\theta$ and $rv_r = -u_\theta$
Both (A) and (C) are equivalent correct forms✔️

Correct Answer Logic:

Polar C-R equations: $\frac{\partial u}{\partial r} = \frac{1}{r}\frac{\partial v}{\partial \theta}$ and $\frac{\partial v}{\partial r} = -\frac{1}{r}\frac{\partial u}{\partial \theta}$, equivalent to $ru_r = v_\theta$ and $rv_r = -u_\theta$.
