American scholars have unearthed groundbreaking evidence suggesting that orchids, a highly diversified plant species, coexisted with dinosaurs. This revelation comes from an analysis of fossilized orchid pollen found on an extinct bee encased in amber, significantly predating previous estimates regarding the age of orchids. The research, spearheaded by a team from Harvard University and featured in the prestigious journal Nature, proposes that orchids could be as ancient as 80 million years, challenging earlier beliefs that pegged their emergence at around 26 million years ago.

Orchids, recognized for their vast diversity and intricate beauty, have long eluded the fossil record, primarily due to their infrequent flowering cycles and preference for humid, tropical climates, which are not conducive to fossilization. However, the discovery of the amber-preserved bee in the Dominican Republic, initially found by a collector in 2000 and later acquired by Harvard's Museum of Comparative Zoology in 2005, has provided a rare glimpse into the ancient history of these plants.

By examining the DNA of the pollen attached to the bee, which is estimated to be 15-20 million years old, researchers employed molecular-clock DNA analysis techniques to trace the lineage of orchids back to their most recent common ancestor, estimated to have lived around 80 million years ago during the Late Cretaceous period. This timeline places the origins of orchids in the era just before the mass extinction event that wiped out the dinosaurs, approximately 65 million years ago, suggesting that orchids may have witnessed the decline of dinosaurs and subsequently flourished across the globe.

The discovery is hailed not only as a critical piece in solving the puzzle of the orchid family's age but also as one of the first instances where direct evidence of ancient pollination, involving both the pollinator and the plant, has been observed. This finding underscores the intricate evolutionary dance between plants and their pollinators, a relationship that has shaped the natural world over millions of years.

1. The passage is primarily concerned with discussing:
A. The role of bees in the pollination process of orchids.
B. The impact of the dinosaur extinction on plant evolution.
C. The discovery and implications of fossilized orchid pollen on understanding plant history.
D. The climate conditions necessary for the preservation of orchids.
E. The debate among scientists regarding the most effective methods for dating fossils.

2. According to the passage, why have orchids been largely absent from the fossil record?
A. Their extensive variety and adaptability.
B. Their predominance in temperate climate zones.
C. Their rare blooming cycle and tropical habitat.
D. Their recent emergence in the evolutionary timeline.
E. Their small size and delicate structure.

3.  The discovery of the fossilized bee with orchid pollen suggests that:
A. Bees were the primary pollinators of orchids during the Late Cretaceous period.
B. The relationship between bees and orchids has remained unchanged for millions of years.
C. Orchids had developed specialized pollination strategies by the Late Cretaceous period.
D. The bee species found in amber is still prevalent in the Dominican Republic.
E. Orchids were more diverse before the dinosaur extinction than previously believed.

4. How was the age of the orchid family estimated by the researchers?
A. Carbon dating of the amber.
B. Examination of the bee's anatomy.
C. Molecular-clock method of DNA analysis.
D. Comparison with other fossilized plants.
E. Analysis of the climate conditions during the Late Cretaceous period.

5. The primary significance of the orchid pollen discovery lies in its ability to:
A. Provide a direct link between extinct and modern orchid species.
B. Confirm the tropical origins of the orchid family.
C. Illustrate the diversity of the orchid family in the prehistoric period.
D. Demonstrate an instance of ancient pollination involving a plant and its pollinator.
E. Challenge previous assumptions about the age of flowering plants.

As an April Fools' joke, a group of Chinese researchers at the Beijing Institute of Acoustics have claimed to develop a novel musical instrument, the "Fool’s Erhu," that they suggest can only be played once a year on April 1st. This instrument allegedly combines various acoustic elements from traditional Chinese instruments but has a mythical pitch range that extends beyond the capabilities of any known instrument.

The researchers presented a fictional pitch range chart for the "Fool’s Erhu," claiming it can produce frequencies starting from as low as 5 Hz to as high as 50,000 Hz, far exceeding the normal hearing range of humans (20 Hz to 20,000 Hz). According to their playful hypothesis, these extreme pitches are said to influence listeners' sense of reality, inducing a state of light-heartedness and joviality appropriate for April Fools' Day.

The following is the purported pitch range of various imaginary instruments created for the joke, all of which have fantastical properties:

"Dragon’s Zither" - Capable of sounds from 15 Hz to 22,000 Hz.
"Phoenix’s Flute" - Emits tones from 25 Hz to 30,000 Hz.
"Qilin’s Qin" - Produces vibrations from 10 Hz to 40,000 Hz.
"Tiger’s Pipa" - Ranges from 20 Hz to 35,000 Hz.
"Turtle’s Gong" - Has a deep tone stretching from 5 Hz to 25,000 Hz.
The researchers jokingly suggested that these instruments could be used in an exclusive concert held on the Great Wall of China, where the vibrations could possibly alter the structure of the wall due to their extraordinary frequency range.
