In the following passage, some words have been deleted. Read the passage carefully and select the most appropriate option to fill in each blank. Palaeontologists are like detectives who (1) ________ the evidence that (2) ______ animals left behind. Those clues to what dinosaurs were like are found in fossils - the ancient (3) _______ of an organism, such as teeth, bone or shell - or (4) _______ of animal activity, such as (5) ________ and trackways.
Select the most appropriate option to fill in blank number 1.
examine
Understanding the Role of Palaeontologists
The passage describes palaeontologists as detectives who study clues left by ancient animals. These clues help them understand what these animals, like dinosaurs, were like.
Analyzing Blank 1: The Detective's Action
The sentence states: "Palaeontologists are like detectives who (1) ________ the evidence that (2) ______ animals left behind." We need to choose the word that best describes what a detective or a scientist does with evidence.
Let's look at the options for blank 1:
- Examine: To inspect something thoroughly to determine its nature or condition. This is precisely what detectives and scientists do with evidence.
- Dominate: To have a commanding influence on; exercise control over. Evidence is studied, not dominated.
- Control: To have power over; direct or determine the behavior or course of. Evidence is studied, not controlled in this context.
- Conduct: To organize and carry out (a particular activity). While scientists conduct studies or experiments, they "examine" or "analyze" the evidence itself. "Conduct the evidence" doesn't make sense grammatically or contextually.
Comparing the options, "examine" fits perfectly with the idea of a detective or palaeontologist carefully studying the clues or evidence found.
Why "Examine" is the Best Fit
Palaeontologists closely study fossils and other traces of ancient life. This careful inspection and analysis of evidence is best described by the verb "examine." The evidence is the 'clues' that ancient animals left behind, such as fossilized bones, teeth, shells, footprints, and trackways. A palaeontologist's work involves detailed examination of these remains and traces to reconstruct the past.
Fossils as Evidence
The passage further explains that the clues are found in fossils, which are the ancient remains or traces of organisms. Examples given are teeth, bone, shell, or traces of activity like footprints and trackways. All these are types of evidence that palaeontologists examine.
Conclusion
Based on the analysis of the role of palaeontologists and the meaning of the options, the most appropriate word to fill blank 1 is "examine". Palaeontologists, like detectives, examine the evidence left behind by ancient animals.
| Option for Blank 1 | Meaning | Fit in Sentence |
|---|---|---|
| Examine | Inspect thoroughly | Fits well; palaeontologists inspect evidence. |
| Dominate | Exercise control over | Does not fit; evidence is studied, not dominated. |
| Control | Have power over | Does not fit; evidence is studied, not controlled. |
| Conduct | Organize and carry out | Does not fit; "conduct evidence" is incorrect phrasing. |
Revision Table: Key Concepts in Palaeontology
| Term | Definition | Relevance to Passage |
|---|---|---|
| Palaeontologists | Scientists who study fossils to learn about ancient life. | The main subject of the passage, described as detectives. |
| Evidence | Facts or information indicating whether a belief is true or valid. | What palaeontologists examine; the clues left by animals. |
| Fossils | The preserved remains or traces of organisms from the past. | The primary type of evidence examined by palaeontologists. |
| Trackways | A series of fossilized footprints made by an animal. | An example of evidence (traces of activity) mentioned. |
Additional Information on Studying Fossils
Studying fossils is a multi-step process for palaeontologists. It often involves:
- Discovery: Finding fossils in the field.
- Excavation: Carefully removing fossils from the surrounding rock or sediment.
- Preparation: Cleaning and preserving the fossils in a lab.
- Examination/Analysis: Studying the fossil structure, composition, and context using various tools and techniques (microscopes, X-rays, chemical analysis). This is where "examine" is key.
- Interpretation: Drawing conclusions about the organism's life, behavior, environment, and evolution based on the evidence examined.
The evidence that palaeontologists examine provides invaluable insights into the history of life on Earth, including details about ancient animals like dinosaurs, prehistoric plants, and even microorganisms.
