Step 1: Understanding the Question
The question asks for a logical inference based solely on the provided underlined sentence. An inference is a conclusion reached on the basis of evidence and reasoning.
Step 2: Analyzing the Underlined Sentence
The key phrases in the sentence are:
- "Many of them...": This is a crucial quantifier. It means a large number, but not necessarily all. Therefore, any conclusion we draw should apply to "some" or "many," but not "all" hummingbirds.
- "...sitting on a dead twig over water...": This phrase explicitly describes the location where these hummingbirds are observed. They are seen hunting in a habitat that is "over water."
- "...catching gnats and other small insects...": This detail reinforces the habitat, as gnats are insects commonly found in swarms near water.
Step 3: Evaluating the Options
(A) Some hummingbirds live in the desert.: The sentence places them "over water," which is the opposite of a typical desert environment. This is not a supported inference.
(B) All hummingbirds live in the desert.: This is incorrect for the same reason as (A), and also because the word "Many" does not allow for a conclusion about "All" hummingbirds.
(C) Gnats are rarely found near bodies of water.: The sentence implies the opposite. Hummingbirds are catching gnats "over water," suggesting that is where gnats are found. This statement is factually incorrect and not supported by the text.
(D) All hummingbirds live near bodies of water.: This is an overstatement. The sentence uses the word "Many," which means we cannot infer this behavior for "All" hummingbirds.
(E) Some hummingbirds live near bodies of water.: This is the most accurate inference. The word "Many" directly supports the conclusion that at least "some" hummingbirds exhibit this behavior, and the phrase "over water" confirms that their habitat is near bodies of water.
Step 4: Final Answer
The sentence states that "Many" hummingbirds are seen "over water." This directly supports the inference that "Some" hummingbirds live near bodies of water.
For the past two years at FasCorp, there has been a policy to advertise any job opening to current employees and to give no job to an applicant from outside the company if a FasCorp employee applies who is qualified for the job. This policy has been strictly followed, yet even though numerous employees of FasCorp have been qualified for any given entry-level position, some entry-level jobs have been filled with people from outside the company.
