Question 2

When glucose is subjected to prolonged heating with HI, the final product obtained is:

Hexanoic acid
6-Iodohexanal
$n$-Hexane✔️
1-Hexene

Correct Answer Logic:

When glucose is treated with HI (hydroiodic acid) on prolonged heating, all the –OH groups are replaced by –I (forming hexaiodohexane), followed by reduction of C–I bonds. This ultimately gives $n$-hexane. This classic reaction confirmed the straight-chain structure of glucose.

Question 3

For a symmetric distribution, Bowley's coefficient of skewness is 0 and Pearson's coefficient $\beta_1 = \dfrac{\mu_3^2}{\mu_2^3}$ equals:

$1$
$0$✔️
$-1$
$3$

Correct Answer Logic:

For a perfectly symmetric distribution, the third central moment $\mu_3 = 0$ (since positive and negative deviations cancel symmetrically). Therefore $\beta_1 = \dfrac{\mu_3^2}{\mu_2^3} = \dfrac{0}{\mu_2^3} = 0$. Note: $\beta_1 = 0$ indicates zero skewness.

Question 4

Oxygenic photosynthesis occurs in:

Chlorobium
Chromatium
Oscillatoria✔️
Rhodospirillum

Correct Answer Logic:

Oscillatoria is a cyanobacterium that performs oxygenic photosynthesis — it uses water as the electron donor and releases O₂ as a byproduct, just like plants. Chlorobium (green sulfur bacteria), Chromatium (purple sulfur bacteria), and Rhodospirillum (purple non-sulfur bacteria) are anoxygenic photosynthesizers — they do not release oxygen.

Question 5

Iodoform ($CHI_3$) can be prepared by the iodoform test from all EXCEPT:

Ethyl methyl ketone ($CH_3COC_2H_5$)
Isopropyl alcohol ($(CH_3)_2CHOH$)
3-Methyl-2-butanone ($CH_3COCH(CH_3)_2$)
Isobutyl alcohol ($(CH_3)_2CHCH_2OH$)✔️

Correct Answer Logic:

The iodoform test is positive for compounds with $CH_3CO–$ or $CH_3CH(OH)–$ groups. Ethyl methyl ketone has $CH_3CO–$ → positive. Isopropyl alcohol has $CH_3CH(OH)–$ → positive. 3-Methyl-2-butanone has $CH_3CO–$ → positive. Isobutyl alcohol ($(CH_3)_2CHCH_2OH$) is a primary alcohol without $CH_3CH(OH)–$ group → does NOT give iodoform test.

A recent national study of the public schools shows that _____, four times as many as there were four years ago.

there are now one microcomputer for every thirty-two pupils, four times as many than there were
there is now one microcomputer for every thirty-two pupils, four times as many than there were
there is now one microcomputer for every thirty-two pupils, four times as many as there were✔️
every thirty-two pupils now have one microcomputer, four times as many than there were

Correct Answer Logic:

There is…one microcomputer' uses the correct singular verb agreeing with singular subject 'one microcomputer.' The comparison must use 'as many as' not 'as many than.' Option A uses plural 'are' with a singular subject. Options B and D use ungrammatical 'as many than.' Option E omits 'there were,' leaving an incomplete comparison.

Psychology QUESTION #1465

Question 15

According to Sigmund Freud, which part of the personality is responsible for the moral and ethical aspects of behavior?

Id
Ego
Superego✔️
Libido

Correct Answer Logic:

In Freud's structural model of personality: the Id (unconscious, pleasure principle — drives and impulses), the Ego (reality principle — mediates between id and reality), and the Superego (the moral and ethical conscience — internalized societal rules and values, includes the conscience and ego-ideal). The superego develops around age 5–6 through the resolution of the Oedipus/Electra complex. Libido is psychosexual energy, not a structural component.

Question 16

The ovarian artery, essential for ovarian blood supply, arises directly from which vessel, explaining its unusually long retroperitoneal course from the abdomen into the pelvis?

The abdominal aorta, just below the origin of the renal arteries✔️
The internal iliac artery
The external iliac artery
The uterine artery

Correct Answer Logic:

The ovarian artery arises from the abdominal aorta just inferior to the renal arteries (reflecting the gonad's original embryological position near the developing kidney) and descends retroperitoneally within the suspensory (infundibulopelvic) ligament to reach the ovary in the pelvis.

Quantitative Reasoning QUESTION #7212

Question 20

The great majority of spacecraft face minimal collision risk from space debris during their active operational periods, but with the increasing number of new satellites being launched each year, the orbital environment going forward is likely to become less _____.

crowded
invulnerable
protected
benign✔️

Correct Answer Logic:

This sentence has a contrast structure: spacecraft currently face little risk, but the future will be less _____. Whatever fills the blank must describe the current relatively safe state that will diminish in the future.

Crowded — the future would logically become more crowded, not less. “Less crowded” contradicts the premise.
Invulnerable — possible in isolation, but not a natural descriptor of an orbital environment as a whole.
Protected — implies external protective mechanisms, which is not the argument’s focus.
Benign — means safe and harmless. The current environment is benign (low risk), and the future will be less benign (more dangerous). This fits perfectly.

Correct Answer: D — Benign. The logic requires a word describing the current “safe” state that will erode as more satellites are launched.
