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 statement is FALSE?
Large vultures fly over Himalayas by gliding.
Analyzing the Excerpt on Bird Classification and Flight
The provided excerpt discusses various aspects of birds, including their classification into orders, the number of species, the characteristics of certain orders like Passeriformes, the survival rates of different groups, and the diversity of flight abilities.
We need to carefully examine each statement provided in the options and determine which one is NOT supported by the information given in the excerpt. Let's break down each statement:
- Statement 1: The order of perching birds contains the largest number of species.
- Statement 2: There are orders of birds that have only one species in them.
- Statement 3: Large vultures fly over Himalayas by gliding.
- Statement 4: The survival rates of primitive orders is low as compared to the evolved ones.
Evaluating Each Statement Based on the Excerpt
Let's compare each statement to the text provided:
- Statement 1 Analysis: The excerpt states, "The order Passeriformes (perching birds) contains the largest number of species." This directly matches statement 1. Therefore, statement 1 is TRUE according to the excerpt.
- Statement 2 Analysis: The excerpt mentions, "Some orders have only one species." This aligns exactly with statement 2. Therefore, statement 2 is TRUE according to the excerpt.
- Statement 3 Analysis: The excerpt states, "the larger vultures are champion gliders". It also mentions that "geese fly over the Himalayas". However, the excerpt does not state that large vultures fly over the Himalayas, nor does it specify where they glide. It only says they are gliders and that geese fly over the Himalayas. Therefore, based *strictly* on the information in the excerpt, this statement cannot be confirmed as true. It is likely FALSE as it makes a claim not supported by the text.
- Statement 4 Analysis: The excerpt explicitly says, "It has generally been found that the survival rate of the primitive orders is much poorer compared to the highly evolved ones." This is exactly what statement 4 says. Therefore, statement 4 is TRUE according to the excerpt.
Identifying the False Statement
Based on our analysis, statements 1, 2, and 4 are supported by the text excerpt. Statement 3, which claims large vultures fly over the Himalayas by gliding, is not mentioned or supported by the text. The excerpt mentions vultures are gliders and that geese fly over the Himalayas, but it does not combine these facts for vultures.
Therefore, the statement that is FALSE based on the provided excerpt is: Large vultures fly over Himalayas by gliding.
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.
