Math Physics Chemistry Biology QUESTION #7735
Question 1

Which substance in semen helps facilitate sperm transport by causing uterine contractions?
  • Androgen
  • Prostaglandinsβœ”οΈ
  • Oxytocin
  • Testosterone

Business, Public administration and Policy QUESTION #10512
Question 2
The increased use of private firms for public service delivery is driven in part by:
  • An ideological conviction that services should be provided by non-state actors wherever possibleβœ”οΈ
  • Increased government financial capacity to pay private organizations
  • A desire to increase direct government involvement in service delivery
  • Efforts to strengthen the governmental role in policy development
Correct Answer Logic:
One key driver of contracting out and privatization is the ideological belief β€” rooted in neoliberalism and Public Choice Theory β€” that market competition and private management inherently produce more efficient, cost-effective services than government bureaucracies. This view gained dominance under Thatcher, Reagan, and subsequent NPM reforms globally, reshaping how governments deliver services.

Question 6
The light can totally pass through the polaroid only if the electric field vector vibrates __________ to the polarizing vector.
  • Antiparallel
  • Parallelβœ”οΈ
  • Opposite
  • None of these
Correct Answer Logic:
A polaroid transmits maximum (100%) intensity when the electric field vector of the incident light is parallel to the polarizing axis of the polaroid. When they are perpendicular, transmission is zero (Malus's Law: \(I = I_0\cos^2\theta\)).

Mathematics QUESTION #7483
Question 8
Let \(A = \{x \in \mathbb{R} : x\) is not a positive integer\(\}\). Define a function \(f: A \to \mathbb{R}\) as \(f(x) = \frac{2x}{x-1}\), then f is:
  • not injective
  • neither injective nor surjective
  • surjective but not injective
  • injective but not surjectiveβœ”οΈ
Correct Answer Logic:
For injectivity: if \(f(x_1) = f(x_2)\), then \(\frac{2x_1}{x_1-1} = \frac{2x_2}{x_2-1}\), giving \(2x_1(x_2-1) = 2x_2(x_1-1)\), so \(x_1x_2 - x_1 = x_2x_1 - x_2\), thus \(x_1 = x_2\). So f is injective. For surjectivity to \(\mathbb{R}\): given \(y \in \mathbb{R}\), solve \(\frac{2x}{x-1} = y\), getting \(2x = yx - y\), so \(x(y-2) = -y\), giving \(x = \frac{y}{2-y}\) (provided \(y \neq 2\)). We need to check if this x is in domain A (not a positive integer). For most y, this x won't be a positive integer, but there are some values of y that map to positive integers, which should be excluded from the range. So f is not surjective to all of \(\mathbb{R}\). The answer is D.

  • Ellipse
  • Parabola

English Literature QUESTION #10703
Question 10
Two words that have very closely related meanings are called:
  • Antonyms
  • Homonyms
  • Synonymsβœ”οΈ
  • Hyponyms
Correct Answer Logic:
Synonyms are two or more words with the same or very closely related meanings. Examples: 'happy/glad/joyful,' 'begin/start/commence.' Antonyms are words with opposite meanings; homonyms are words that sound the same but have different meanings (e.g. bank); hyponyms are words that are specific members of a broader category (e.g. 'rose' is a hyponym of 'flower').

Question 12
Molarity of heavy water \((\text{D}_2\text{O})\):
  • 55.5 mol dm\(^{-3}\)
  • 60.5 mol dm\(^{-3}\)
  • 40.5 mol dm\(^{-3}\)
  • 50.5 mol dm\(^{-3}\)βœ”οΈ
Correct Answer Logic:
Molarity of heavy water \(= \dfrac{\text{density} \times 1000}{\text{molar mass}} = \dfrac{1.105 \times 1000}{20} \approx 55.5\) mol dm\(^{-3}\). Note: The paper marks 50.5 but the accepted value is ~55.5.

Question 13
In Marlowe's Doctor Faustus, Faustus asks two magicians to aid him in summoning the devil. What are their names?
  • Valdes and Corneliusβœ”οΈ
  • Rosencrantz and Guildenstern
  • Troilus and Cressida
  • Pyramus and Thisbe
Correct Answer Logic:
In Marlowe's Doctor Faustus, Faustus is aided by Valdes and Cornelius β€” two learned magicians who teach him the art of necromancy and help him prepare to summon Mephistopheles. Rosencrantz and Guildenstern are characters from Shakespeare's Hamlet; Troilus and Cressida and Pyramus and Thisbe are also Shakespearean pairs.

Agronomy QUESTION #2035
Question 14
The optimum harvest index (HI) of modern high-yielding wheat varieties compared to traditional tall varieties is higher because:
  • Modern varieties produce more total biomass per unit area
  • Modern varieties partition a greater proportion of total biological yield into the economic yield (grain), with HI values of 0.45–0.55 vs 0.30–0.35 in traditional varietiesβœ”οΈ
  • Modern varieties have shorter grain-filling periods, reducing respiration losses
  • Modern varieties have thicker stems that store more assimilates
Correct Answer Logic:
Harvest Index = Economic yield / Biological yield. Green Revolution breeding shifted assimilate partitioning toward grain by reducing stem height (dwarfing genes Rht1, Rht2), increasing HI from ~0.30 in tall varieties to 0.45–0.55 in semi-dwarf modern varieties β€” the primary mechanism behind yield gains.

Agriculture Economics QUESTION #11895
Question 15
Market equilibrium occurs where:
  • Quantity supplied exceeds quantity demanded
  • Quantity demanded equals quantity supplied at the prevailing price, $Q_d = Q_s$βœ”οΈ
  • Price equals average cost
  • Total revenue is maximized
Correct Answer Logic:
Equilibrium is the price-quantity point at which $Q_d = Q_s$: the quantities buyers wish to purchase and sellers wish to offer are exactly equal.

  • Accounting provides an opinion; Auditing provides the facts
  • There is no distinction; they are the same activity
Correct Answer Logic:
Accounting is the systematic recording and reporting of financial info, while auditing is the concern with whether that info reflects a true and fair view.

Question 20
Which of the following conditions is most suitable for the conversion of hexane into benzene?
  • $Sn / HCl$
  • $V_{2}O_{5}$ at $500^{\circ}C$βœ”οΈ
  • $LiAlH_{4}$
  • $Zn-Hg / HCl$
Correct Answer Logic:
The conversion of alkanes (like n-hexane) into aromatic hydrocarbons (benzene) is known as aromatization or catalytic reforming. This is achieved by heating the alkane to high temperatures (approx $500^{\circ}C$) in the presence of oxides of vanadium ($V_2O_5$), chromium, or molybdenum supported over alumina.
