  1. fossils

  2. embryos

  3. mountains

  4. vestigial organs

A Correct answer
Explanation

Fossils are preserved remains/traces of organisms that show evolutionary changes over time. They provide direct physical evidence of species that lived in different eras. Embryos show developmental similarities, mountains are geological, and vestigial organs (like wisdom teeth) are evidence but less direct/evident than fossils.

Multiple choice

Mesozoic Era is the era of

  1. fishes

  2. reptiles

  3. birds

  4. plants

B Correct answer
Explanation

The Mesozoic Era (Triassic, Jurassic, Cretaceous periods) is famously called the 'Age of Reptiles' when dinosaurs dominated terrestrial ecosystems. While birds evolved from theropod dinosaurs during this era and plants continued to diversify, reptiles (particularly dinosaurs) were the dominant vertebrates. Fishes were most prominent in earlier periods.

Multiple choice

Paleontology is the study of

  1. embryos

  2. DNA

  3. fossils

  4. human race

C Correct answer
Explanation

Paleontology is the scientific study of fossils and the history of life on Earth as revealed by the fossil record. Paleontologists examine fossilized remains to understand extinct organisms, evolutionary patterns, ancient ecosystems, and geological time periods.

Multiple choice

Directions: The sentence below or part thereof has been underlined. The underlined part may have an error of grammar or diction. Select the option that best corrects the error, if any.

Paleontologists believe that fragments of a primate jawbone unearthed in Burma and estimated at 40 to 44 million years old provide evidence of a crucial step along the evolutionary path that led to human beings.

  1. at 40 to 44 million years old provide evidence of

  2. as being 40 to 44 million years old provides evidence of

  3. that it is 40 to 44 million years old provides evidence of what was

  4. to be 40 to 44 million years old provide evidence of

  5. as 40 to 44 million years old provide evidence of
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

the subject 'Jawbone' is an object and it has to be followed by pronoun 'it', which is not used in any other option except (C), so (C) is the answer.

Multiple choice

The correct chronological sequence of periods of Pleistocene Ice Age is

  1. Riss-Gunz-Wurm-Mindel

  2. Gunz-Mindel-Riss-Wurm

  3. Mindel-Riss-Gunz-Wurm

  4. Riss-Wurm-Gunz-Mindal

B Correct answer
Explanation

The four major glacial stages of the Pleistocene in the Alps, from oldest to youngest, are Gunz, Mindel, Riss, and Wurm. They are often remembered by their alphabetical order.

Multiple choice

Tertiary period had five epochs. Select the correct order in which these epochs appeared in the geological time scale from ancient to more recent times.

  1. Palaeocene-Oligocene-Miocene-Eocene-Pliocene

  2. Palaeocene-Pliocene-Oligocene-Miocene-Eocene

  3. Oligocene-Palaeocene-Miocene-Eocene-Pliocene

  4. Palaeocene-Eocene-Oligocene-Miocene-Pliocene
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The Tertiary period is divided into five epochs in chronological order: Paleocene, Eocene, Oligocene, Miocene, and Pliocene. This sequence represents the progression of geological time from approximately 66 million to 2.6 million years ago.

Multiple choice

Match List I with List II and select the correct answer: List I List II (Geological period) (Event associated with the period) A. Carboniferous 1. Start of Himalayan Orogeny B. Pre-cambrian 2. Birds made there appearance C. Pleistocene 3. Formation of rocks containing coal, petroleum and natural gas D. Upper Cretaceous 4. Large areas subject to glaciation 5. Rock formation having rich metallic materials

  1. A 5 B 3 C 2 D 4

  2. A 3 B 5 C 4 D 1

  3. A 5 B 3 C 4 D 1

  4. A 3 B 5 C 2 D 4
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Carboniferous period is famous for vast coal-forming swamps (3). Pre-cambrian rocks are the primary source of ancient metallic ores (5). The Pleistocene is the epoch of recent major glaciations (4). The Upper Cretaceous/Early Cenozoic marks the beginning of the tectonic movements leading to the Himalayas (1).
