Directions: Read the following excerpt and answer questions asked at the end. The answers to the questions should be based on the excerpt. Today birds inhabit every continent. There are nearly 9000 species classified into 27 orders. Some orders have only one species. The order Passeriformes (perching birds) contains the largest number of species. The most evolved birds are found in the Passeriformes order - sparrows, finches, crows, jays etc. It has generally been found that the survival rate of the primitive orders is much poorer compared to the highly evolved ones. The ability to fly - like many other biological properties of living beings - came about as an adaptation to particular conditions. The variety of habitats and the varied responses to them has led to an incredible diversity of flight techniques. Sparrows cannot glide; the larger vultures are champion gliders but cannot take-off without a run into the wind. Penguins and ostriches cannot fly; geese fly over the Himalayas. It would appear as if no two species fly exactly the same manner.
Which of the following inferences can be drawn from the above excerpt?
To order with the largest numbers of species is also the most evolved.
Analyzing Bird Orders and Evolution from Excerpt
The provided excerpt discusses the classification of birds into orders and species, highlighting characteristics like flight ability, survival rates, and evolution. It specifically mentions the Passeriformes order.
Evaluation of Options based on the Excerpt:
Let's examine each option in light of the information given in the passage:
-
Option 1: "To order with the largest numbers of species is also the most evolved."
The excerpt states, "The order Passeriformes (perching birds) contains the largest number of species." It then immediately follows with, "The most evolved birds are found in the Passeriformes order - sparrows, finches, crows, jays etc." This directly links the order with the largest number of species (Passeriformes) to being the one where the most evolved birds are found. Therefore, this inference is supported by the text. -
Option 2: "All the 27 orders have at least two species in them."
The excerpt explicitly states, "Some orders have only one species." This contradicts the statement in option 2. Thus, this inference cannot be drawn. -
Option 3: "Biological properties of living beings is a result of diversity of flight techniques."
The excerpt says, "The ability to fly - like many other biological properties of living beings - came about as an adaptation to particular conditions." It frames flight as a biological property resulting from adaptation, not that *all* biological properties are a result of the diversity of flight techniques. This inference misinterprets the text. -
Option 4: "All living beings that can walk can also fly."
The excerpt gives examples of birds like penguins and ostriches that "cannot fly" but can certainly walk. This directly contradicts the statement in option 4. Thus, this inference cannot be drawn.
Based on the analysis, only Option 1 is a valid inference that can be drawn directly from the provided excerpt.
Important Questions from Passage Based Questions
Read the following passage and answer the questions based on it.
As climate change affects seasonal patterns, water management and distribution become important. Rainwater harvesting has become particularly important in urban areas these days. This process involves collecting and storing rainwater for later use. It recovers groundwater levels, prevents water wastage during the monsoon, reduces soil erosion and helps in the availability of drinking water. Above all, it promotes the method of water conservation.
This paragraph supports which of the following statements the most?
A. Climate change has adversely affected humanity.
B. Forests help maintain groundwater levels.
C. Rainwater harvesting is the need of the hour.
D. There are not enough water reserves for urban areas.
Which of the following inferences can be drawn from the above excerpt?
Which of the following statement is FALSE?
According to the excerpt what led to the diversity of flight techniques?
Which of the following statements is WRONG in the context of the above excerpt?
