Fill in the blanks with an appropriate tense form.
1Pakistan successfully ............... its nuclear-capable, radar-dodging cruise missile on July 26.
Wrong!
The definite past time "on July 26" makes "test-fired" the correct simple past form.
2Australia ............... 40% of the world's known uranium reserves.
Wrong!
A general fact about Australia takes the simple present form "holds".
3The Union Cabinet ............... the landmark civilian nuclear cooperation agreement with the USA in March.
Wrong!
The definite past time "in March" makes "approved" the correct simple past form.
4A group of students ............... an environmentally friendly Eco One race car.
Wrong!
For recent news without a finished-time expression, "have built" is the best choice.
5A powerful earthquake ............... Japan on July 16, killing and injuring several people.
Wrong!
The definite past time "on July 16" makes "hit" the correct simple past form.
6After analyzing thousands of skulls, British scientists have arrived at the conclusion that modern humans ............... from a single point in Africa.
Wrong!
The conclusion refers to a past origin, so "originated" is the natural tense here.
7Scientists think they ............... the energy source of the spectacular colour displays seen in the Northern Lights.
Wrong!
For recent scientific news, "have discovered" is the best choice.
8The world's oceans, which absorb about a third of the carbon dioxide emitted from burning fossil fuels, ............... more acidic.
Wrong!
An ongoing change happening now is expressed with "are becoming".
9Babylonians were the first to make New Year resolutions, and people all over the world ............... them ever since.

With "ever since", the continuing action is best expressed by "have been breaking".

Wrong!
A repeated habit in the past can be expressed with "would trudge".
11The world's oldest city ............... in the deserts of Peru, or so believes a group of archaeologists.
