Chemistry QUESTION #7402
Question 9681
Which of the following oxides is NOT expected to react with sodium hydroxide?
  • BeO
  • \(\text{B}_2\text{O}_3\)
  • CaO✔️
  • \(\text{SiO}_2\)
Correct Answer Logic:
Reaction with NaOH (basic): Only acidic or amphoteric oxides react with NaOH.
  • BeO: amphoteric → reacts with NaOH
  • B₂O₃: acidic → reacts with NaOH
  • CaO: basic → does NOT react with NaOH (two bases don't react)
  • SiO₂: acidic → reacts with NaOH → Na₂SiO₃

Question 9687
In the gravity model of spatial interaction, what does the distance decay exponent 'b' represent?
  • Population growth rate between locations
  • Barrier effect of distance on interaction✔️
  • Economic development differential
  • Transportation cost per unit distance
Correct Answer Logic:
The exponent b (typically 1-3) represents the friction or barrier effect of distance. Higher b values indicate greater distance decay - interaction decreases more rapidly with distance. It varies by interaction type: social visits (high b), freight movement (low b).

Statistics QUESTION #2012
Question 9691
In the LSD (Least Significant Difference) test for comparing treatment means in ANOVA, two means \(\bar{y}_i\) and \(\bar{y}_j\) are declared significantly different if:
  • Their difference exceeds \(t_{\alpha/2, df_E} \cdot s_e\)
  • Their difference exceeds \(t_{\alpha/2, df_E} \cdot \sqrt{\dfrac{2 MS_E}{b}}\)✔️
  • Their difference exceeds \(F_{\alpha, 1, df_E} \cdot MS_E\)
  • Their difference exceeds \(z_{\alpha/2} \cdot SE\)
Correct Answer Logic:
The LSD test declares means significantly different if \(|\bar{y}_i - \bar{y}_j| > LSD\), where \(LSD = t_{\alpha/2, df_E} \cdot \sqrt{\dfrac{2 MS_E}{b}}\). This is the critical difference computed from the t-distribution with error degrees of freedom and the standard error of the difference between two means.

Administration QUESTION #9565
Question 9700
The principle of 'crowding out' in public finance describes a negative externality of government borrowing. Explain the precise mechanism by which excessive government borrowing from the domestic banking sector crowds out private investment.
  • Government borrowing increases money supply, causing inflation, which reduces real returns on private investment
  • Government borrowing absorbs available credit in the banking system, reducing funds available for private lending, which raises interest rates and suppresses private sector investment and economic growth✔️
  • Government borrowing forces banks to hold government securities instead of foreign exchange, reducing private firms' ability to import capital goods
  • Government borrowing is repaid through higher future taxes, which reduces consumer spending and therefore reduces the demand that private firms invest to meet
Correct Answer Logic:
When government borrows extensively from domestic banks, it competes with private borrowers for a finite pool of lendable funds. This drives up interest rates (cost of credit), making private investment more expensive and less profitable — reducing private capital formation. This is the crowding out mechanism that classical economists warned about and why fiscal discipline is considered essential for private sector growth.
