AA Digital SAT 3 - BlueBook App Test

Day by day, the work assumed greater precision,
and settled its irregular and misty outline into
distincter grace and beauty. The general design
was now obvious to the common eye.

I HEAR it is charged against me that I seek to destroy institutions;
But really I am neither for nor against institutions
(What indeed have I in common with them? Or what with the destruction of them?),
Only I will establish in the Mannahatta [Manhattan] and in every city of These States, inland and seaboard,
And in the fields and woods, and above every keel [ship] little or large, that dents the water,
Without edifices, or rules, or trustees, or any argument,
The institution of the dear love of comrades.

• Severo Ochoa discovered the enzyme PNPase in 1955.
• PNPase is involved in both the creation and degradation of mRNA.
• Ochoa incorrectly hypothesized that PNPase provides the genetic blueprints for mRNA.
• The discovery of PNPase proved critical to deciphering the human genetic code.
• Deciphering the genetic code has led to a better understanding of how genetic variations affect human health.

• Physicist Muluneh Abebe was working on a garment suited for both warm and cold conditions.
• He analyzed the emissivity, or ability to emit heat, of the materials he planned to use.
• Abebe found that reflective metal fibers emitted almost no heat and had an emissivity of 0.02.
• He found that silicon carbide fibers absorbed large amounts of heat and had an emissivity of 0.74.
• The amount of heat a material absorbs is equal to the amount of heat it emits.

• In the early 1960s, the US had a strict national-origins quota system for immigrants.
• The number of new immigrants allowed from a country each year was based on how many people from that country lived in the US in 1890.
• This system favored immigrants from northern Europe.
• Almost 70% of slots were reserved for immigrants from Great Britain, Ireland, and Germany.
• The 1965 Hart-Celler Act abolished the national-origins quota system.

• In 2020, theater students at Radford and Virginia Tech chose an interactive, online format to present a play about woman suffrage activists.
• Their "Women and the Vote" website featured an interactive digital drawing of a Victorian-style house.
• Audiences were asked to focus on a room of their choice and select from that room an artifact related to the suffrage movement.
• One click took them to video clips, songs, artwork, and texts associated with the artifact.
• The play was popular with audiences because the format allowed them to control the experience.

Go forth, my son,
Winged by my heart's desire!
Great reaches, yet unknown,
Await
For your possession.
I may not, if I would,
Retrace the way with you,
My pilgrimage is through,
But life is calling you!

As a fragile and lovely flower unfolds its gleaming
foliage on the breast of the fostering earth, if
the dew and the rain draw it forth;
So doth my tender mind flourish, if it be fed with the
sweet dew of the fostering spirit,
Lacking this, it beginneth straightway to languish,
even as a floweret born upon dry earth, if the
dew and the rain tend it not.

• Some sandstone arches in Utah's Arches National Park have been defaced by tourists' carvings.
• Park rangers can smooth away some carvings using power grinders.
• For deep carvings, power grinding is not always feasible because it can greatly alter or damage the rock.
• Park rangers can use an infilling technique, which involves filling in carvings with ground sandstone and a bonding agent.
• This technique is minimally invasive.

• Soo Sunny Park is a Korean American artist who uses light as her primary medium of expression.
• She created her work Unwoven Light in 2013.
• Unwoven Light featured a chain-link fence fitted with iridescent plexiglass tiles.
• When light passed through the fence, colorful prisms formed.

We mean nothing but a little amusement among ourselves, just to vary the scene, and exercise our powers in something new. We want no audience, no publicity. We may be trusted, I think, in choosing some play most perfectly unexceptionable, and I can conceive no greater harm or danger to any of us in conversing in the elegant written language of some respectable author than in chattering in words of our own.

Perhaps ten-year-old John was puzzling to the folk there in the Florida woods for he was an imaginative child and fond of day-dreams. The St. John River flowed a scarce three hundred feet from his back door. On its banks at this point grow numerous palms, luxuriant magnolias and bay trees. On the bosom of the stream float millions of delicately colored hyacinths. [John Redding] loved to wander down to the water's edge, and, casting in dry twigs, watch them sail away down stream to Jacksonville, the sea, the wide world and [he] wanted to follow them.

Lily had no real intimacy with nature, but she had a passion for the appropriate and could be keenly sensitive to a scene which was the fitting background of her own sensations. The landscape outspread below her seemed an enlargement of her present mood, and she found something of herself in its calmness, its breadth, its long free reaches. On the nearer slopes the sugar-maples wavered Ilke pyres of light: lower down was a massing of grey orchards, and here and there the lingering green of an oak-grove.

• In 1999, astronomer Todd Henry studied the differences in surface temperature between the Sun and nearby stars.
• His team mapped all stars within 10 parsecs approximately 200 trillion miles) of the Sun.
• The surface temperature of the Sun is around 9,800°F, which classifies it as a G star.
• 327 of the 357 stars in the study were classified as K or M stars, with surface temperatures under 8,900°E (cooler than the Sun).
• 11 of the 357 stars in the study were classified as A or E stars, with surface temperatures greater than 10,300°F (hotter than the Sun).

• One of history's greatest libraries was the House of Wisdom in Baghdad, Iraq.
• It was founded in the eighth century with the goal of preserving all the world's knowledge.
• Scholars at the House of Wisdom collected ancient and contemporary texts from Greece, India, and elsewhere and translated them into Arabic.
• Writings included those of the Greek philosopher Aristotle and the Indian mathematician Aryabhata.
• The House of Wisdom used Chinese papermaking technology to create paper versions to be studied and shared.

• Ducklings expend up to 62.8% less energy when swimming in a line behind their mother than when swimming alone.
• The physics behind this energy savings hasn't always been well understood.
• Naval architect Zhiming Yuan used computer simulations to study the effect of the mother duck's wake.
• The study revealed that ducklings are pushed in a forward direction by the wake's waves.
• Yuan determined this push reduces the effect of wave drag on the ducklings by 158%.

• The magnificent frigatebird (fregata magnificens) is a species of seabird that feeds mainly on fish, tuna, squid, and other small sea animals.
• It is unusual among seabirds in that it doesn't dive into the water for prey.
• One way it acquires food is by using its hook-tipped bill to snatch prey from the surface of the water.
• Another way it acquires food is by taking it from weaker birds by force.
• This behavior is known as kleptoparasitism.
