The correct statement regarding this situation is ().

E) Wan's appeal cannot be supported because the new Criminal Law does not have retroactive effect on judgments that have already taken effect.

Choices:
Wan's appeal can't proceed, for laws enacted later don't impact prior legal decisions.
Wan's appeal cannot be supported, but his sentence could be reduced.
Wan's appeal should be dismissed because the original sentence was severe and justifiable.
Wan's appeal cannot be supported, and his suspended sentence should also be revoked and replaced with actual imprisonment because he did not comply with supervision.
Wan's appeal cannot be supported because the new Criminal Law does not have retroactive effect on judgments that have already taken effect.

Question: A purchaser signed an agreement of sale to buy real estate. It had a contingency clause requiring him to make a completed application for a mortgage within a specified time. It said that time was of the essence. The purchaser failed to apply but instead asked a mortgage broker friend for his opinion as to whether he would qualify. The seller told the purchaser that she rescinded the sale because there was no mortgage application within the agreed time. A few days later, the purchaser made a belated application and received approval, but the seller insisted on a rescission of the contract. Will the seller likely prevail in rescinding the transaction?

E) Yes, because the purchaser did not make a timely application and lost the protection of the contingency clause.

Choices:
Yes, because the purchaser did not fulfill the conditions of the contingency clause in the specified time.
Yes, because the purchaser did not formally submit a mortgage application, violating the agreement.
No, because the amount of time that he was late was a "de minimus" delay that should not preclude him from the benefit of the bargain.
Yes, because the seller has the right to rescind the sale at any time.
Yes, because the purchaser did not make a timely application and lost the protection of the contingency clause.
No, because the purchaser's discussion with a mortgage broker should be considered as an attempt to apply.
No, because the original request to his mortgage broker friend was a timely application within the spirit of the agreement.
No, because the approval of the belated application should allow the transaction to proceed.
Yes, because she rescinded the sale prior to his notifying her of the approval  the first notice communicated is the effective one.

Hence must it lamentably be against the testimony of Christ Jesus for the civil state to impose upon the souls of the people a religion, a worship, a ministry, oaths (in religious and civil affairs), tithes, times, days, marryings, and buryings in holy ground..."

Question: Why is the basicity of amines stronger than that of alcohols or phenols?

B) The electronegativity of a nitrogen atom is less than that of an oxygen atom. The bonding ability on the amino nitrogen atom is stronger.

Choices:
Amines have lower activation energy to form alcohols, which directly influences their inherent basicity.
The electronegativity of a nitrogen atom is less than that of an oxygen atom. The bonding ability on the amino nitrogen atom is stronger.
Structural variations in amino groups increase hydrogen bonding, unlike hydroxyl groups in alcohol.
Alcohols have strong covalent bonds that limit their ability to donate electrons, impacting their basicity.
Amines have a polar C-N bond, while alcohols form stable hydrogen bonds in water. This factor reduces basicity.
Nitrogen in amines can acquire a positive charge, making it more acidic compared to alcoholic protons.
The presence of hydroxyl groups vastly improves the capacity of alcohols to sustain resonance than amines.
The presence of lone pairs in oxygen reduces the likelihood of forming bonds, affecting alcohol basicity.
The aromatic nature of phenols significantly enhances the electron-withdrawing effect from hydroxyl oxygen.
The hydroxyl group in alcohols stabilizes the oxygen atom through resonance. The interaction weakens basicity.

Question: A car with a mass of 1275 $\mathrm{kg}$ is brought to a stop from a speed of 60,000 m/h by braking, reducing its speed to 20,000 m/h. Assume that during the braking process, the $0.5 \mathrm{kg}$ brake pad and the $4 \mathrm{kg}$ steel brake drum are uniformly heated, but no heat is transferred to the outside. Given that the specific heat capacities of the brake pad and the steel brake drum are $1.1 \mathrm{kJ} / (\mathrm{kg} \cdot \mathrm{K})$ and $0.46 \mathrm{kJ} / (\mathrm{kg} \cdot \mathrm{K})$ respectively, calculate the temperature increase of the brake pad and the brake drum.
