PASSAGE

The new smartphone update promises to ______ battery life, allowing users to go longer between charges.

Which choice completes the text with the most logical and precise word or phrase?

A. shorten
B. extend✓ Correct
C. deplete
D. complicate

Detailed Explanation

If users can go longer between charges, the duration of the battery has increased. 'Extend' means to make longer or wider.

Key Evidence:

• "battery life"

• "go longer between charges"

Why others are wrong: A (Shorten means to make less, the opposite of going longer.), C (Deplete means to use up, which would shorten the life.), D (Complicate implies making difficult, which is unrelated to duration.).
