Biology Zoology Botany QUESTION #1343

Erythropoietin, a hormone, is primarily produced by _________ and is involved for RBC production:

Liver
Kidney✔️
Leukocytes
None of these

Correct Answer Logic:

Erythropoietin (EPO) is a glycoprotein hormone primarily produced by peritubular interstitial cells in the cortex of the kidney (about 90%) in response to hypoxia (low oxygen levels). A small amount is produced in the liver. EPO stimulates the bone marrow to increase the production of red blood cells (erythropoiesis), thereby increasing oxygen-carrying capacity.

Mathematics QUESTION #6940

Question 1283

Find the number of surjective (onto) functions $f$ from $\{1,2,3,\ldots,20\}$ to $\{1,2,3,\ldots,20\}$ such that $f(k)$ is a multiple of 3 whenever $k$ is a multiple of 4.

$6^5 \times (15)!$
$5! \times 6!$
$(15)! \times 6!$✔️
$5^6 \times 15$

Correct Answer Logic:

Multiples of 4 in $\{1,\ldots,20\}$: $\{4,8,12,16,20\}$ — 5 elements. Their images must be multiples of 3 in $\{1,\ldots,20\}$: $\{3,6,9,12,15,18\}$ — 6 elements.

Assign the 5 multiples-of-4 to 5 of the 6 multiples-of-3 (injectively, since $f$ is onto): $6 \times 5 \times 4 \times 3 \times 2 = 6!/(6-5)! = 720$... but we need surjection on all 20 elements.

The remaining 15 domain elements map to the remaining 15 codomain elements (after fixing the 5 images above): $(15)!$ ways. But 1 multiple-of-3 is unused by the multiples-of-4, so it must be covered by remaining 15 elements.

Total $= 6! \times (15)! = (15)! \times 6!$

Economics QUESTION #1699

Question 1286

Which Nobel Prize-winning economist conceptualised the framework of 'Development as Freedom,' arguing that development must be evaluated by the expansion of human capabilities and substantive freedoms?

Paul Samuelson
Amartya Sen✔️
Milton Friedman
None of these

Correct Answer Logic:

Amartya Sen, the Indian economist and Nobel Laureate (1998), articulated the 'Development as Freedom' framework in his landmark 1999 book of the same name. He argued that development should be understood as the expansion of real freedoms people enjoy — including political freedoms, economic facilities, social opportunities, transparency guarantees, and protective security. This approach influenced the UNDP's Human Development Index (HDI) and reoriented development economics beyond GDP growth.

Tourism & Hospitality Management QUESTION #1610

Question 1290

In the Front Office Operations course, 'overbooking' is discussed as a front office practice. Which management strategy best justifies its controlled use?

To maximize staff utilization during quiet periods
To offset anticipated no-shows and cancellations, ensuring maximum occupancy and revenue while managing the risk of walking guests✔️

When practiced strategically, it is used to offset predictable no-show rates and last-minute cancellations — maximizing occupancy. The course covers its relationship with yield management and the front office procedures for managing 'walked' guests when overbooking results in excess arrivals.

Civil Engineering QUESTION #2119

Question 1299

In the moment distribution method for analyzing indeterminate structures, the distribution factor (DF) for a member at a joint is defined as:

The ratio of the member stiffness to the sum of stiffnesses of all members meeting at the joint✔️
The ratio of the fixed-end moment in the member to the total applied moment at the joint
The carry-over factor multiplied by the member stiffness
The ratio of span length to total length of all members at the joint

Correct Answer Logic:

Distribution Factor $DF = \dfrac{K_{member}}{\sum K_{members\,at\,joint}}$, where $K = \dfrac{4EI}{L}$ for far-end fixed and $K = \dfrac{3EI}{L}$ for far-end pinned. The sum of DFs at any joint always equals 1.0 (except at fixed supports where DF = 0). The DF determines what fraction of the unbalanced moment is distributed to each member at a joint.
