Question:
This question refers to the following information.
Read the following memoir.
Not only did he expect all persons of distinction to be in continual attendance at Court, but he was quick to notice the absence of those of inferior degree; at his lever, his couches, his meals, in the gardens of Versailles (the only place where the courtiers in general were allowed to follow him), he used to cast his eyes to right and left; nothing escaped him[;] he saw everybody. If anyone habitually living at Court absented himself he insisted on knowing the reason; those who came there only for flying visits had also to give a satisfactory explanation; anyone who seldom or never appeared there was certain to incur his displeasure. If asked to bestow a favor on such persons he would reply haughtily: "I do not know him"; of such as rarely presented themselves he would say, "He is a man I never see"; and from these judgments there was no appeal.
No one understood better than Louis XIV the art of enhancing the value of a favor by his manner of bestowing it; he knew how to make the most of a word, a smile, even of a glance.
He loved splendor, magnificence, and profusion in all things, and encouraged similar tastes in his Court; to spend money freely on equipages and buildings, on feasting and at cards, was a sure way to gain his favor, perhaps to obtain the honor of a word from him. Motives of policy had something to do with this; by making expensive habits the fashion, and, for people in a certain position, a necessity, he compelled his courtiers to live beyond their income, and gradually reduced them to depend on his bounty for the means of subsistence.
-Duke Saint-Simon, Memoirs of Louis XIV and His Court and His Regency, c. 1750

He was so concerned with ceremonies and appearances that he did not rule his country well.
He failed to modernize France's military, leaving it vulnerable to foreign attacks.
He was too focused on architectural projects, neglecting the needs of his people.
He left the administration of his kingdom to professional bureaucrats known as intendants.
He was at war for 2/3 of his reign and united the other major powers against him.

Question:
Ce nouveau film d'animation s'appuie sur une histoire originale d'Alexandre Astier : Astérix - le secret de la potion magique.
Il y a quatre ans, Alexandre Astier et Louis Clichy avaient plutôt séduit la critique avec _Le Domaine des dieux (2014)_, un film d'animation qui faisait rire les adultes comme les enfants. Avec ce nouvel opus, _Astérix - le secret de la potion magique_, les mêmes réalisateurs ne renouvellent pas tout à fait la performance. L'idée de départ était pourtant séduisante. Plutôt que d'adapter un album existant de René Goscinny et Albert Uderzo, Alexandre Astier a obtenu le droit d'écrire une histoire originale, assez inventive.
Après avoir chuté d'un arbre, le druide Panoramix décide qu'il est temps pour lui de prendre sa retraite et de chercher un(e) successeur(e) à qui il transmettra le secret de la potion magique. Le voilà donc parti à la recherche du candidat idéal à travers la Gaule, en compagnie d'Astérix et Obélix. Si les premières minutes du film sont enlevées, et annoncent une certaine folie douce, la suite est plus laborieuse. Le recrutement s'éternise, les gags s'enchaînent sans grande surprise et à toute vitesse, au détriment de l'image. Le dessin est lisse et stéréotypé. Ses couleurs chatoyantes, son esthétique télévisuelle manquent de poésie.
Heureusement, de nouveaux petits personnages apportent un peu de piment. Ainsi, Alexandre Astier a créé un nouveau méchant. Sulfurix, qui va jouer les trouble-fête - un peu comme la vilaine fée au début de _La Belle au bois dormant_. Dans le passé, Sulfurix n'a jamais digéré de n'avoir pas été élu druide, face à Panoramix. Diabolique, il est aussi plein d'intelligence, lorsque, de retour parmi les Gaulois, il déclare à propos de la potion magique : « Moi, si j'avais disposé d'une telle puissance, je ne l'aurais pas gardée pour quarante crétins à moustache, j'aurais arrêté toutes les guerres du monde. »
Moins centré sur Astérix, le film est plus collectif, embarquant des personnages secondaires à la forte personnalité, telle la petite Pecüne, jeune Gauloise surdouée qui n'est pas qu'un astérisque et va jouer un rôle décisif. Un Astérix dans l'air du temps.Sur la base du texte ci-dessus, répondez aux questions suivantes. Sur la base du texte ci-dessus, répondez aux questions suivantes.

Question: Which of the following statements about the formation of upslope winds is correct?

F) It is caused by cold air descending the slope at night due to mountain temperature differences and warm air rising during the day.

Choices:
It occurs due to warm air sinking at night and cold air rising during the day on slopes.
It happens when warm air accumulates at the bottom of a slope and pushes colder air upwards.
It is a result of warm air rising from the valley at night and cold air descending during the day due to temperature differences.
It arises when warm air rises from the base during the day and cold air descends at night.
It occurs when there is significant ground variation and strong surrounding winds.
It is caused by cold air descending the slope at night due to mountain temperature differences and warm air rising during the day.
During the day, sunlight heats the air layer close to the slope, causing the warm air to descend along the slope and cold air to rise from the valley to replenish it, creating an airflow from bottom to top.
It originates when cold air rises from the valley at night and warm air descends during the day.
It results from warm air accumulating at the summit, pushing colder air downwards during the day.
At higher altitudes, wind speeds are faster, so wind blows from lower to higher altitudes.
