Practice questions

Q1Select the most appropriate one-word substitute: A large building in which aircraft are kept

A Depot
B Hangar
C Garage
D Harbour
Explanation

A hangar is a large building used to house and maintain aircraft. Depot, garage, and harbour refer to other storage or shelter places for goods, cars, or ships.

Q2Select the most appropriate one-word substitute: Branch of science that deals with earthquakes

A Geology
B Meteorology
C Palaeontology
D Seismology
Explanation

Seismology is the science that studies earthquakes and the propagation of seismic waves. Broader or neighbouring earth sciences are not the exact one-word match.

Q3Select the most appropriate one-word substitute: A person who loves or collects books

A Bibliophile
B Librarian
C Publisher
D Manuscript
Explanation

A bibliophile is a person who loves or collects books. Librarian and publisher work with books in institutional or commercial roles, and a manuscript is a document rather than a person.

Q4Select the most appropriate one-word substitute: one who always expects favourable outcomes.

A Optimist
B Idealist
C Fatalist
D Realist
Explanation

An optimist habitually expects favourable outcomes. Idealist, fatalist, and realist name other outlooks—principle-driven hope, belief in fate, and hard-headed acceptance—so only optimist fits.

Q5Select the most appropriate one-word substitute: The scientific study of birds

A Entomology
B Zoology
C Ornithology
D Anthropology
Explanation

Ornithology is the branch of science devoted to birds. Related life-science labels such as entomology or zoology name different fields and are not exact substitutes.
