Answer:
Toward
Explanation:
Let's take a look at this sentence you have provided : Head toward the large yellow sign to find the lemon grove.
Before we can solve this problem, we need to develop a understanding of what a preposition is and what to look out for.
Prepositions are defined as a word which shows a relationship between other words in a sentence.
This typically is seen in cases of direction, time, place, amount, cause and matter.
Once you understand this, you can then take a look at the answer choices you've provided.
Head
Toward
Yellow
Lemon
We can now easily remove two options from this selection based on our new definition.
This leaves us with Head or Toward as our answer options.
Head is used to describe an action, however does not provide direction/time/place etc..
Toward is used to describe an area of direction and also provides spatial clarity.
Thus giving us the answer of toward as a preposition!
