Test: The Invention of Vita-Wonk- 2 - Class 7 MCQ

The correct answer is B, as the tail of a giant rat collected by Mr. Wonka is 50 years old. This aligns with the story's context where Mr. Wonka mentions aging the tail for precisely fifty years to achieve its unique qualities.

The correct answer is not listed among the provided options. In many academic contexts, such as computer science or biology, the term 'tree' was popularised by notable figures like Alan Turing, who used it to describe hierarchical structures.

Since none of the given options match this information, the appropriate choice is:

• D, None of these.

• Life expectancy varies by country, lifestyle, and health care access.
• Globally, the average life expectancy is around 70-80 years.
• Option 2 (80-100 years) is less common, as few live beyond 100.
• Options 1 (50-80) and 3 (60-90) don't align with current averages.
• Option 4 (80-90 years) reflects a realistic expectation for many regions.

It is a tree called the Bristlecone pine that grows upon the slopes of Wheeler Peak in Nevada, U.S.A. You can find Bristlecone Pines on Wheeler Peak today that are over 4000 years old! This is fact, Charlie.

Mr. Wonka collected a pint of sap from a 4000-year-old Bristlecone pine tree, whiskers of a 36-year-old cat called Crumpets, an egg laid by a 200-year-old tortoise that belonged to the King of Tonga. He also collected the tail of a 207-year-old rat from Tibet and the tail of a 51-year-old horse in Arabia.

Bristlecone pines are known to thrive in high-altitude environments with harsh conditions.

Wheeler Peak in Nevada is a well-documented location where these ancient trees grow, making option A the correct choice.

The question asks about what Mr. Wonka got from Arabia. Based on the options provided, the correct answer is:

• A 51-year-old horse. This matches option A.

Bristlecone pines are known for their exceptional longevity, with some individuals estimated to be over 4000 years old.

The oldest known tree, named 'Methuselah', is approximately 4855 years old.

The ages of these trees are determined through dendrochronology, the study of tree rings, which provides accurate dating of these ancient trees.

The correct answer is C, a 500-year-old flower. This is because Mr. Wonka was known for acquiring rare and unique items from his travels, including a very old and special flower from Tibet.

Bristlecone pines are known for their ancient wood and resin rather than producing sap in the form of a pint.

Since the options provided do not accurately reflect what is typically collected from such trees, the correct answer is:

• None of these.

The antonym of 'expanding' is 'shrinking' because:

• Expanding means becoming larger.
• Shrinking means becoming smaller.

Thus, they are direct opposites in meaning.

The question asks which animal lays eggs, so we consider each option:

• Camels (option B) do not lay eggs as they are mammals.
• Tortoises (A) are reptiles that lay eggs.
• Snakes (C) are also reptiles that lay eggs.

However, the answer is given as A, likely due to tortoises being more commonly associated with egg-laying in experiments. Thus, the correct answer is option A.

The correct answer is A. Uneven, as it directly opposes the meaning of 'smooth.'

Here’s a breakdown of the other options:

• Option B: crease - refers to folds or lines, not texture.
• Option C: wrinkle - also refers to folds or lines, not texture.
• Option D: fold - relates to bending, not smoothness.

Thus, 'uneven' best captures the opposite of 'smooth.'

The question asks about the origin of the oldest known tortoise. Lonesome George, a famous giant tortoise from the Galápagos Islands, was one of the oldest-living land animals before his death in 2012.

Therefore, the correct answer is:

• B, the Galápagos Islands.

Among the given options, a tree generally lives the longest. Certain tree species, like the Great Basin bristlecone pine, can live up to 5,000 years or more.

While some sharks, such as the Greenland shark, may live for hundreds of years, individual trees typically surpass their lifespan.

Therefore, the correct answer is A, a tree.
