Sociology QUESTION #1675

Question 3

Robert K. Merton proposed a methodological and theoretical middle path between abstract grand theory and atheoretical empiricism in sociology, advocating for formal, logically interconnected propositions of limited scope that could be empirically tested. He called these:

Macro-sociological paradigms
Grand unified theories of social action
Middle-range theories✔️
Grounded theoretical frameworks

Correct Answer Logic:

In 'Social Theory and Social Structure' (1949), Merton criticized both Parsonian grand theory (too abstract to test) and raw empiricism (too disconnected from theory). He advocated for 'theories of the middle range' — formal, testable theories of limited scope (e.g., relative deprivation, reference group theory) that bridge empirical research and broader theoretical frameworks.

Mathematics QUESTION #7471

Question 5

If the vectors $\vec{AB} = 3\hat{i} + 4\hat{k}$ and $\vec{AC} = 5\hat{i} - 2\hat{j} + 4\hat{k}$ are the sides of a triangle ABC, then the length of the median through A is:

$\sqrt{18}$
$\sqrt{72}$
$\sqrt{33}$✔️
$\sqrt{45}$

Correct Answer Logic:

The median from A goes to midpoint M of BC. Position vector of B from A is $\vec{AB} = 3\hat{i}+4\hat{k}$, and of C from A is $\vec{AC} = 5\hat{i}-2\hat{j}+4\hat{k}$. Midpoint M has position vector $\frac{\vec{AB}+\vec{AC}}{2} = \frac{(3\hat{i}+4\hat{k})+(5\hat{i}-2\hat{j}+4\hat{k})}{2} = \frac{8\hat{i}-2\hat{j}+8\hat{k}}{2} = 4\hat{i}-\hat{j}+4\hat{k}$. Length of median $AM = |\vec{AM}| = \sqrt{16+1+16} = \sqrt{33}$.

Question 7

A patient is prescribed Lugol's Solution ($5\%$ iodine) $0.3$ mL three times daily. What is the total daily iodine dose?

$15$ mg
$30$ mg
$45$ mg✔️
$90$ mg

Correct Answer Logic:

$5\%$ iodine $= 5\ \text{g}/100\ \text{mL} = 50\ \text{mg/mL}$. Each dose $= 0.3 \times 50 = 15\ \text{mg}$. Three doses $= 15 \times 3 = 45\ \text{mg}$ per day.

Question 13

If $a < b$ and $c < 0$, then $ac$:

$< bc$
> bc✔️

Chemistry QUESTION #7414

Question 14

The acidity of diprotic acids in aqueous solution increases in the order:

$\text{H}_2\text{S} < \text{H}_2\text{Se} < \text{H}_2\text{Te}$✔️
$\text{H}_2\text{Se} < \text{H}_2\text{S} < \text{H}_2\text{Te}$
$\text{H}_2\text{Te} < \text{H}_2\text{S} < \text{H}_2\text{Se}$
$\text{H}_2\text{Se} < \text{H}_2\text{Te} < \text{H}_2\text{S}$

Correct Answer Logic:

Acid strength of hydrides (Group 16):
Down the group, bond length increases (H–X bond gets weaker), making it easier to release H⁺. Therefore acid strength increases down the group:

$\text{H}_2\text{O} < \text{H}_2\text{S} < \text{H}_2\text{Se} < \text{H}_2\text{Te}$

Note: This trend is opposite to electronegativity trend, and is governed by bond dissociation energy.

Chemistry QUESTION #7150

Question 15

Identify the amphoteric hydroxide among the following group 2 elements.

$Be(OH)_{2}$✔️
$Ca(OH)_{2}$
$Mg(OH)_{2}$
$Sr(OH)_{2}$

Correct Answer Logic:

Most group 2 hydroxides are basic and their basicity increases down the group. However, Beryllium ($Be$) is the first element and shows diagonal relationship with Aluminum. Due to its small size and high electronegativity, $Be(OH)_{2}$ is amphoteric, meaning it reacts with both acids and strong bases.

Dairy Food Science and Technology QUESTION #5925

Question 20

In standardization of milk using the Pearson Square method to produce $3.5\%$ fat milk from full-fat milk ($6\%$ fat) and skim milk ($0.1\%$ fat), the proportion of full-fat milk required is:

$\dfrac{3.4}{5.9}$ parts full-fat milk per total✔️
$\dfrac{3.5}{6.0}$ parts full-fat milk per total
$\dfrac{0.1}{5.9}$ parts full-fat milk per total
$\dfrac{2.5}{5.9}$ parts full-fat milk per total

Correct Answer Logic:

Pearson Square: desired fat $= 3.5\%$. Parts full-fat $= 3.5 - 0.1 = 3.4$. Parts skim $= 6.0 - 3.5 = 2.5$. Total $= 3.4 + 2.5 = 5.9$. Proportion of full-fat milk $= \dfrac{3.4}{5.9}$.
