English grammar — Spot the error (choose the segment that contains a grammatical error; choose ‘‘No error.’’ if the sentence is correct). Sentence: We play tennis together every morning since last June.

Introduction / Context:
This item tests tense selection with “since.” When an action started in the past and continues to the present, English requires the present perfect (often progressive), not the simple present.

Given Data / Assumptions:

• “Since last June” gives a starting point in the past.
• The action (playing tennis together) continues up to now.
• The habitual adverbial “every morning” is compatible with a present perfect progressive describing an ongoing routine.

Concept / Approach:
Use “have/has been + -ing” (present perfect progressive) with “since + point in time.” Use “for + duration” if a length of time is specified.

Step-by-Step Solution:

Verification / Alternative check:
Corrected sentence: “We have been playing tennis together every morning since last June.”

Why Other Options Are Wrong:

Final Answer:
We play
